Yeah, knowing your swing and how it affects ball flight relative to ball flight laws is great for making the most of any ball flight monitor, I'd think. I'd agree that a few calculated parameters (if the science/numbers are good) isn't a killer either...depending on what information is crucial to you and your particular faults. Certain systems may be more insightful for readily available bits of info than others.
Here's an interesting thing I just noticed on TM re spin axis. Their new patent may give them a direct measurement of spin rate, but it seems that the spin axis is imputed based on the ball flight (where the ball starts and ends up).
I don't think in the Titleist video that the spin axis actually tilted much off horizontal. The ball curved primarily due to differential lift/drag on opposite sides of the ball, which I expect is what's happening with mud balls (dimples covered on one side).
I've never heard of range balls causing a club face to crack. But, if it does happen again, they should replace it under warranty like the other two, so I wouldn't worry about it.
Any time there is a crack in a clubhead or if a weld fails it will cause a loss in performance. It's impossible to say how much of a loss because every instance is different, but it's never a good thing.
That's not why you were called a jerk. @iacas probably thought, as I did when I just read it, that it was more of reference to this quote, "You give a poor man a fish and you feed him for a day. You teach him to fish and you give him an occupation that will feed him for a lifetime".
Which could be interpreted that all we did was give you "tips" and not actually help you.
@natureboy, you can do whatever you want, I don't care. If you can turn your hips fully and not change the address flex in the knee, good for you. Film it because I think it's extremely difficult.
I can come up with a long list of HOF players and major winners that lose some flex in the trail leg during the backswing.
Maintaining address flex has zero advantages over losing a few degrees of flex.
You're exaggerating what I'm saying. I said push not "thrust" back.
The pressure loads into your trail heel. You don't "need" to do it, it just happens (when you turn your hips properly).
From pics 1-2 is their right glute getting closer or staying the same distance from the "wall" (I didn't draw the lines btw). It's clearly getting closer, it would be "pushing" into the wall, like I said.
What do you think is happening here? Is Rory maintaining his address knee flex? Heck no.
