Hello here is my first review for MX-S rubbers , got two sheets of them with maximum 2.1 mm sponge attached them on my old stratus powerwood blade, considering that i upgrades from softer rubbers ( andro rasant bh, dhs hurricane 8 mid-hard) first of all, after the first hold and first few balls i found that the blade is really heavier than before, stratus PW notorious for head heavy, and also mx-s are one of the heaviest! giving the whole combo good power when playing with good technique and fast full movement, the main problem till now is that i am not finding myself well yet, i dont have the same control as before for BH, MX-S is not forgiving at all, u should play very good technique to get sth from this rubber, till now i can't generate that enormous spin that i heard about, the spin i generate is good , almost like the one with DHS or fastarc G-1 , but it is harder to obtain that amount, i didn't find mx-s as very fast rubber, it is just speed enough when u play good technique, if you play passively this rubber is almost dead, noting that i am using all-wood 5 plies blade.. the best thing so far with this rubber is the serve recieve and small touches.. it's so controllable with good feeling to place the ball in desired spot while keeping it short.. i played for 4 sessions till know, the rubber needs to be cleaned to maintain its grip quality, i think i need to develop my physical skills to fit this rubber more.. and hope i will decode its secrets with more training sessions.
