- What is C.O.R.? What is CT?
- What is the difference between a variable thickness and uniform thickness clubface?
- Why are the Fairway Wood Lie Angles More Flat than the Driver Lie Angles on Most of Your Sets of Woodheads, When the Standard for Decades has been to make Driver Lie Angles more Flat than Fairway Woods?
- Why is the Face Thickness a Different Dimension for the Various Driver and Fairway Wood Models, such that some Drivers are Thinner than Other Drivers, or some Fairway Woods are even Thicker than some Drivers?
- What is the best combination of impact launch parameters for a golfer?
- What does the term “Bend Profile” mean with respect to shaft design and fitting?
- Why are some of your Driver designs made with Hook face angle while others are Square?
- What do the various numbers and letters that are used to describe metals in clubmaking mean? I mean things like 10-2-3 Titanium, SP700 Titanium, 455 Steel, and so forth?
- I hear the term "Heat Treated" sometimes used in conjuction with presenting a particular clubhead design. What does that mean?
- What determines how you choose the various dimension specifications for an iron design, such as toe height, heel/crotch height and blade length?
- Why do you design your iron sets with the headweight of the PW higher than the #9-iron?
- What is the difference between a Titaniumwoodhead that is made from multiple pieces welded together compared to one that is made by investment casting, or forging?
- There are so many different Titaniumalloys that are used to make Drivers these days. What is the difference between them and is there one over all others that is best for performance?
- Why do some TitaniumDrivers today sell for under $50 while others sell for over $100?
- Many companies like to list the type of carbon steel used in their forged ironheads. What is the difference between carbon steels like 1030, 1045, S45C, 1050 and others like that, and why are different carbon steels used for forging irons?
- What is the 5-step forging process that you describe you do on your Wishon Golf 550C and 550M forged iron heads and how does that differ from the way other companies make forgings?
- What makes a good face material for a driver?
- How does the actual spring face of a driver work to increase ball velocity? Is it like a 'slingshot' where the face flexes back and then snaps forward to launch the ball?
- How much does a face deflect inward when it is made to be thin?
- What is vertical gear effect and does it help improve shot performance?
- In the 1980s shaft torque was talked about a lot as a factor for shaft fitting, while now it is rarely mentioned. Is the torque of a shaft important anymore in shaft fitting?
- Why does TWGT design its drivers and woods with Graduated Roll Technology (GRT)?
- In the optimization of the launch parameters of launch angle, spin rate and ball velocity, how much can the club itself affect a change in the backspin rate?
- I have golfers who are concerned if they switch to a higher loft driver head to gain more launch angle and with it, more carry distance, that the increase in the loft/launch angle will cause them to hit the ball so high that the shot will be harder to control, whether from wind or from more miss-direction tendencies. What can be done about that?
- How is the best way to determine if a golfer is going to be successful with a much longer driver? I have many senior golfers come to me with ever decreasing distance as a complaint and think that a 46, 47 or 48" driver will be their answer to gaining that distance back.
- What really is the effect of offset on ball flight as a clubhead design specification?
- What determines actually how much an ironhead can be bent for a loft and/or lie angle adjustment? And can Titaniumwoods be bent for face angle or lie change?
- What is Moment of Inertia and why is it important in golf equipment performance?
- What is the effect of a clubhead’s Center of Gravity (CG) on shot performance?
- What are the key elements of shaft fitting?
- Will a longer club hit the ball farther?
- How should a golfer choose between hybrid clubs and fairway woods when both may hit the ball the same distance?
