Just to clarify, are you saying the amount of the spin is mostly caused by the Line of Compression? Does speed play a part? Does loft play a part? Is HK also assuming a centered strike? He goes on to say in 2-C-0 that maximum compression is the ideal result. Where can I find his definition of compression? nevercrosses View Public Profile Find all posts by nevercrosses
