Paul B. - 11 Dec 2018
After playing with my last sheet on my forehand, I ordered a red 2.1 for my backhand. The red sheet was noticeably more tacky than the black sheet I first ordered, and I was concerned this would affect the qualities I valued the first time around. After a few hours of play the extra tackiness fell off a bit but it still produced great spin and speed yet the blocks were just a little tougher than before. Overall it really is a versatile rubber.
