Butterfly Feint AG???

So I've tried out the Feint AG 1,3mm in black, on a Grubba Carbon ALL+, and Sriver FX 2,1mm on the forehand.

Looping was pretty easy compared to the Feint 2 OX, still had to hit harder and pull it a bit more than with the inverted rubber. Chopping I is also easier than with the feint 2 ox. The disturbing effects on the other hand are much lower compared to the feint 2, doesn't have too much spin reversal, more of a dead ball goes back to the opponent, but they said the still had to pull tha ball harder when looping compared to and inverted. Dropping back topspins seemed fairly easy with it, it's still not too sensitive to spin, but more than the feint 2, so a slightly closed bat angle has to be used. I'm glad I've got the 1,3mm and not the 1,7mm. It's pretty fast, the control is pretty good, not as easy as with the feint 2 but probably it's because it's a bit more reactive to spin. Still my technique sucks, but when I managed to hit with it the ball had some kind of strange sinking path, not like when you hit with an inverted. Serve returns can be done similar to the feint 2 ox, but some adjustments need to be done since it reacts more to spin. I still need to learn to play with it, but I think it's going to be better for me than the feint long 2 ox. But this review is based on 3 hours of play, so it's not close enough to get used to a rubber.
