I didn't even get that far. I stopped paying attention at:

[i]Are you using a very flexible shaft? Guess what, the more flexible the shaft, the lower the energy transfer to the ball, due to shaft deflection at impact.[/i]

If you kept reading and took in proper context:...
"Fortunately, most equations that invoke the law of conservation of momentum have variables that are negligible in a practical sense, so they can be thrown out in most cases (i.e. don't worry about the sound of your driver, the energy loss is negligible to it's effects on distance)."
[/quote]

Yes, I did see it. But those "variables" mentioned (shaft flex, how soft/firm the hands, sound) are not valid variables that just happen to be "negligible" in the context of the swing, they are not actually valid variables to begin with and should never have been mentioned in the first place.

I guess I missed a lot!

A high CT head doesnt even mean you will hit it further or better, most companies have not even found the magic CT number to match a players swing speed. Lots of things come into play with a CT migrating higher as you hit it as well, from B&R to thickness of face, as well metal used and the Rockwell hardness. So much, that its very very very very hard for OEM clubs to have a head that will not move up in migration of CT numbers. They will most likely stay stag as they are cast and painted. Its been fun these years on the back side of this info and helping start the foundation of migration issues and working with lots of variable to see what makes what happen.

So is a 249 CT head extremely difficult to come by? What exactly would I notice here in reality from a regular manufactured head?

You are mostly just paying for a number when you see the "hot" CT tested heads. The actual difference between one you normally see that is on the low side vs a "hot" head is measured in decimal points of ball speed differences, not whole numbers. If a half MPH of ball speed is worth the extra cost then go for it.

As has been stated, most of the Tour heads you will see are in the low to mid 240 range for CT. The difference between that and 257 is basically nothing. Maybe 2-3 yards, which nobody is hitting a driver pure enough 100% of the time to ever really notice that. As long as it's around 240 or better don't even worry about it.

Tour guys are not playing hot heads. TM would never put a driver in a players hand that is anywhere near that 257 mark. The very minimal gain in distance isn't worth it.

Until you miss that bunker carry by 2-3 yards and curse your underspec'd dead driver. :D

What's difference between a CTA and CTB score?

[mflores]

same question as above

 

What is the COR A and COR B?

[Jc0]

Can't say for sure but probably just a redundant test to make sure your first reading was accurate.

Interesting topic. Could someone explain some of the numbers on this Tour head label?

 

I understand Lie, Loft, FA, WT.

What's the difference between CTA & CTF ?

 

What are RA1: RA2: HT: T: H: & LH ?

 

Thanks

Twist face head. Numbers show how much twist is in the head.

Thanks. Much appreciated

I just bought this M6 head. I’ve seen a USGA official show and explain the CT testing and he said they test all over the face. Never mentioned what or where CTA, b, or f are but for anyone in the know am I to assume this is a “hot head” ? Sorry I know this is an older thread but I’m curious

[storm319]

Those are simply different test points on the face. They likely chose 3 fairly common locations on the face to make certain that all results are under the limit. As for which point on the face that each one of those designations represents, I have no idea.
