We all get way too caught-up in this Ball Spin stuff. In todays world of Golf, things have leveled / evened-out to where there is really not that big of a difference in Ball A vs Ball B. Sure in the olden days of the wound Titleist vs say standard Top-Flights their were huge differences. Today thru technology manufactures have created non-urethane covered balls that act almost like urethane. Upgrades in core materials and layers have also closed the old gap to where most balls have practically the same characteristics.
The specifications for Legal Golf Balls are narrowly defined, therefore all the various manufacturers produce products that act all but the same. Ball Weight, size, ball speed, design, performance, ect... must fall within these very narrowly defined specifications.
It's the Marketing and Advertising schemes / angles that make us think there are major differences. There are not.
Give Mickelson, Couples or Mahan, a TF Gamer, Maxfli VT4, a Wilson Staff Zip, or any decent ball and they will learn its slight nuances and eventually shoot the same scores they do with their current Highly Marketed Balls. Just like the groove change which affected spin, a Ball change will not increase Tour average scores, at least not enought to be noticable.
