Ok I got an Inspirit along with my Stradivarius, and thought I would comment on it. First impression is it's pretty hard, and heavier than typical jap/euro rubbers. If I were to compare it to any rubber it would be Killerspin Fury. Heavy, fast, reacts to priming very well, and pretty responsive to your motions. The rubber is quite bouncy, and actually much more fun to play than what I remember about the Saviga. However when I played my Saviga I didn't prime, or use EEII. Both softened the sponge quite a bit. I put this on my backhand cause I was looking for a non tacky less reactive to incoming spin for my backhand. This did a fairly good job of this, but the Black side is much more reactive to incoming spin than the red side of typical Dawei rubbers. Control game is good, speed was excellent, blocking was great. Keep in mind this is all being done on my new Stradivarius which is the highest control OFF rated blade I have played with, and does seem to lend a hand toward higher throw. The throw of the Inspirit is medium from what I can tell. I hate talking throw as it seems that some have different definitions of throw. Serving has pretty good action on them. There really aren't any shots you can't do with Inspirit, but I'm not as picky as most. It seems everyone makes some statement about all rubbers that they can hit this shot, but can't hit that shot. Nothing seems overwhelmingly difficult with the Inspirit, and I would totally recommend this rubber to someone looking for a cost alternative to euro rubbers. Oh, and the durability of Dawei rubbers is far and away better than both jap and euro rubbers. If they could get their weight down a little bit I would probably stop looking for a backhand rubber.
