So Federer always hits his forehand with the same side of the buttcap in his palm and so always hits his forehand with the same side of the racquet face. He hits his backhand with the other side.
Even Justine Henin, who had semi-western grips on both forehand and backhand (pretty much the same grip for both, try it) switched side from forehand to backhand, probably for the same reason: the shape of the buttcap.
ok. I had seen fish when playing the other day had the black up but later in the match had the red up so i thought there was maybe something different w feds.. but then i wasnt sure because federer seems to hit with a lot of different grips from all sides so was wondering if there was anything too extreme going on with the grip
