This is the sort of rubber that requires very good technique, but sadly not the european kind; to really get the most out of this rubber you need to have a huge looping forehand, but if you misjudge it it's likely to go horribly wrong. Serves can be very good, especially when the rubbers new, the ball rarely pops up too high. Overall a good rubber if you're willing to really work for it, but there are easier alternatives.
