the original idea was that balls wont break on your hand as easy as they would on your mask, the wiping was added later*g*. stuff like that could be the edge when you are a frontplayer. i mean it could be the thing between get shot or not, just like always hold your marker behind your body when running on the tape(when you are breaking to a bunker on the left tape, hold marker in the left hand and the other way round) cause balls that hit you might bounce, if they hit your marker they wont.
