It might be the MXS sponge. It is not a catapult sponge. So it is on the slower side of things and you really have to put in the effort with that rubber.
thanks carls .im heard about omega 4 asia had also little catapult effect and also mxs .i play mainly brush looping of third ball.with 4 asia my brush loop is fast n enough spin.with mxs .mxp. 05 and omega v asia that the ball have more spin and drop of speed compare to omega 4 asia.why is that happen ? any similar rubber for brush looping aside omega 4asia for upgrade my level?i played ascuda s1 and it is not better than omega 4asia and not worse than this.
Bad glue job?
I find my MXS to be quite fast and to have quite a noticable catapult effect... but maybe that's just me, admittedly, I haven't played MXP
