Bounce: In a wedge, bounce is the angle of the sole as measured from the ground plane in a square hit position. Typically, the trailing edge is below the leading edge, which can be a lot or a little, depending on sole width and bounce angle. The optimum bounce angle or degree is designed into wedges to prevent the leading edge from digging, which can stop the momentum of the club and result in loss of intended distance.

Bulge and Roll: Bulge is the toe-heel or horizontal curvature of the face in wood designs. Roll is the top-bottom or vertical curvature of the clubface. Bulge and roll are used to direct the ball in terms of initial ball direction and spin, working to compensate for gear effect spin, which is induced when the ball is impacted in a way that its center of gravity is offset from that of the clubhead.

Clones vs Name Brands: You know the most popular big name brand companies in golf today. We don't have to tell you. These companies are just working off each other with innovative new product concepts, materials and fashion statements. Our goal is to provide all of the performance features of a big name brand with a better value to you. Clones are not to be confused with the big name brand products. We don't have to pay for commericals or be a sponsor. Clones are made from the same basic materials and design principles. We buy our heads, shafts, and grips from the same small community of golf manufacturing suppliers. The real important part is we provide performance and try to offer you a GREAT VALUE.

Center Of Gravity: The center of gravity or CG is the small point which represents the intersection of all the possible balance points of that object. CG in a golf clubhead, can be determined by balancing the head any place on the head. The intersection inside of the head of all these different balance points is the center of gravity of the clubhead. The lower the CG and the farther back the CG is from the face of the club, the higher the trajectory of the shot will be for any given loft angle on a clubhead.The horizontal CG, or how far the CG is over from the center of the shaft, is a design factor that affects the accuracy of the shot. The closer the CG is to the shaft, the less tendency there will be for you to push or fade the ball offline. The closer the CG is to the shaft, the lower the MOI about the shaft axis will be, and the greater the tendency will be for you to rotate the face of the club less open. The farther the CG from the shaft, the higher the MOI will be about the shaft axis, and the greater the tendency for the you to leave the face of the club more open by the time the head contacts the ball.

CNC: Computer Numerical Control; a type of machining where the material cutting and the associated tool paths are controlled by a computer for precision. The computer is pre-programmed by an operator using a "definition" of how the object will ultimately look. In the case of a clubhead, the "definition" is a CAD model of the head. The CNC technique reduces the risk of human error during machining, allowing tighter tolerances and more consistent machining.

Draw Bias: The strategic placement of weight in a clubhead, which helps to square it at impact, lessening the chance of hitting a slice and increasing chances of hitting a distance-increasing draw. Draw Bias counteracts the spin that typically creates a slice, and helps to create the spin necessary to hit a satisfying shot.

Frequency Match: Frequency is defined simply as a method of dynamically determining the stiffness feel of a golf shaft. The frequency of a shaft is measured in vibration cycles as a function of time. For a raw, uncut shaft the butt end is secured in a clamp. A prescribed weight is attached to the tip end. By pulling the weight down and releasing, a meter calculates cycles per minute. When building a set of frequency matched clubs, shafts with the same cycles per minute readings are selected.

Lie Angel: Lie angle is defined as the centerline of the shaft with the ground line tangent to the sole at the face center line. Lie angles are described as too upright, too flat or correct. A lie angle that is too upright will cause the ball to be hit left of the target and a lie that is too flat will cause the ball to be hit right of the target for a right handed golfer. There are a lot of factors involved with getting the right lie angle including your height, arm length, stance, as well as club length.

Loft Angle: The angle of the face to the centerline of the hosel is called loft. The more highly lofted a club is, the higher will be the trajectory of your ball. Drivers, 1 and 2 irons have very low loft angles while wedges have high loft angles. Loft angles are expressed in degrees with respect to vertical rather than the ground. There is also a natural progression in the loft of your irons from 1-PW which is a factor in determining the distance you hit each iron. Changing the loft on your irons is similar to using a different lofted driver. Your irons can be changed to match your desired launch angle. Bending the loft of an iron weakens the hardened metal and can lead to future metal fatigue, since the actual bend twists the metal. We suggest changing clubs to change the loft. Example 6 iron to a 7 iron.

Milled Face Putter: When putters are made with a Milled Face they are simply taking a Computer Numeric Control machine and running the putter's face through the Computer Numeric Control process. The Computer Numeric Control process makes the face to the exact loft and also makes the face perfectly straight. It removes any variations the face may have. It's a great way to ensure precision. You can tell if a putter has been milled by seeing slight circular waves on the face from the Computer Numeric Control machine.

Moment Of Inertia: Moment of inertia means a clubhead's resistance to twisting when the ball is hit. If your swing is a little off and you hit the ball on the toe of the clubhead, a clubhead with a higher MOI will twist less as a result of the mis-hit. Thus creating a better chance that the ball will go where you intended and with less loss of distance. The term Moment of inertia or MOI is becoming much more common in advertising by golf club companies. The term is directly related to the growth in popularity of ever-larger clubheads, both for drivers and putters. The size and weighting properties of a clubhead can be manipulated to add a greater MOI. High-MOI is an important component in clubs that are described as forgiving or game improvement.

Offset: The position of the hosel relative to the leading edge, or forward-most edge on the sole of a club. The offset is the distance that the hosel sits in front of the leading edge of the club, and it allows the average player slightly more time to square the clubface to target before impact.

Steel Shafts vs Graphite Shafts: Over the years there has been discussions concerning graphite shaft vs steel shaft. With modern manufacturing techniques and material these differences have narrowed. Graphite shafts are lighter and feel softer. It will assist the slower swinger to maintain clubhead speed and provides some shock absorption. Steel shafts are heavier and firmer. They provide more feel and accuracy than graphite with a sacrifice in distance. If you notice we recommend graphite with our drivers and fairway woods for distance however steel in our irons and hybrids for accuracy.

Spine Alignment: A spine can be visualized as a longitudinal line or plane on a golf shaft. Every shaft also has a Neutral Bend Point or NBP and the shaft wants to twist too that position. By locating the shaft spine it can be placed in a predetermined position. We prefer to place the Neutral Bend Point in the predetermined position. Depending on the position of the shaft's Neutral Bend Point, the graphics will be in an undetermined position when the shaft is installed.

Swing Speed: This is a comparison of shaft characteristics based on actual test results of the cut frequency, torque, tip and butt deflections. It shows how a shaft is relate to a player's swing speed and tempo. To get the correct shaft, first determine your swing speed. If you don't know your swing speed, it can be determined by going to our Fitting Chart page.

Swing Weight: A measurement representing the balance and mass distribution of a golf club. The measure is on an arbitrary scale (C1, D1, D0, etc.) from a club's balance point or fulcrum at 14 inches from the butt end.

Titanium Material: The reason why 15-3-3-3 or SP 700 is the premier titanium to manufacture heads is the fact that it is both stronger and has a high rate of elongation. The more elongation the easier it is to make the face Spring, and because the tensile strength is higher it will not break even though it is flexing or Springing more than a 9-6AL-4V titanium. The face can also be made thinner with 15-3-3-3 and SP 700 beta titanium because the additional strength and elongation. The thinner the face, the better the rebound effect and longer the shot. Which is good for you. However keep in mind that most titanium heads just have the higher grade titanium in the face area but there are exceptions. The cost for 15-3-3-3 Beta is typically about three times more than 9-6AL-4V. The cost for SP700 Beta is typically about six times more than 9-6AL-4V.

Torque: Torque is defined as the amount of twisting of a shaft around its axis. A lower torque shaft normanly has a stiffer feel and is more stable, a higher torque shaft is vice versa. Low handicap players could use a lower torque shaft. High handicap players and those who slice the ball, should have a higher torque shaft. One thing to keep in mind is that as driver heads get larger and clubs are constructed longer the more torque or twisting is placed on the shaft. The torque is low enough on steel shafts that it is usually not a factor when selecting.
