is the only difference between the 2, more spin in 802-40?
is 802 more faster/controllable than the 40?
since theres spin in the 802-40, is it almost like an inverted rubber when blocking?
Having used both extensively, I feel both have equal amount of spin but in different applications. 802-40 can produce stronger loops and devastating blocks due to its larger pips, but regular 802 wins in spin and accuracy in pushing and chopping by a large margin. For technical players I'd recommend regular 802, and 802-40 for those who love to play hard and fast.
