I LOVE this rubber, it's my new FH. Not bad for a rubber that is ~3years old. I first tried it on my friends rosewood blade and its still performs as well on my zetro quad. I think this rubber is compatible with any blade. This is the fastest and the spinniest rubber i've tested so far (>T05, powergrip/grip, calibra tour M.... etc). Lighter than most max rubbers and less than $40 at ttjapan. (Durability is still a question mark). The reviews for this rubber is no joke, FAST, SPINNY and FORGIVING... If i have to say something negative about this rubber, im going to have to say that it's not as spinny on serves as the H3neo (but thats just coz of its tackiness :P), other than that, i would have given this rubber a 10/10 on the spin rating
