according to tuxen......backspin degrades by....

[Michael Finney]

4% every second of flight...

for those who care

6000 rpms with 5 seconds of flight would translate to 4892 at touch down....

I guess I never really thought about it. Would depend on ball type and dimple type too yes?

A fastball leaves the pitcher's hand at 92 and gets to the batter at around 84.

One of my highlights of the PGA Show was the Trackman stuff; both at the AMF meeting and at the Trackman booth. I'd love to have one at my club. The price tag is still a choker for me.
