some would bother to do slow motion comparison of a "pro"
hitting a "spinning" type shot and a mediocre player hitting the exact same shot a very small difference would be seen ----- the small difference is a difference , however. SOME differences are the difference between teaching and touring , also.

weird if you ask me.
My solution is to outlaw high speed video , then anyone can say anything they want without challenge.
