The 'shop bounce test' has always amused me but its amazing how many people believe the results

The amount a ball can be deformed (compressed) is the key. Find a ball that compresses best for your game. If it compresses too much then you need a higher compression ball. Its why ladies balls are not much use of most men.

Paul,

Are you aware of any published studies that support the thesis of increased yardage for 'average' players -- those with slower clubhead speeds -- using a low compression Ball versus a higher compression Ball? Or any other work that would shed authoritative light on this subject? [Unsupported advertiser's claims and recommendations don't fit the definition.] I don't claim to be an expert in this area and would like to know more. As an example, I've never tested the 'average' lady to see if she can hit a 'ladies Ball' further than a 'men's' high compression Ball. My assumption is she cannot, but surely there must have been at least some empirical work done to support this separate product line.

I can tell you that Homer Kelley believed that the higher compression Ball offered superior performance for all classes of players. Ever practical, however, he also stated, "If they can't take advantage of [the better Ball because they're always duffing it], then 'ten cent pickups' will work just as well."
