Nihonjihn-it doesn't help if you mash as fast as possible, since you can do it too fast so the opponents gets free, often unpunished and not hit by a smash, are you scared of a "random" IC-player beating you in a tournament before brawl is released?
I heard that Svampens Nana hit you kinda hard at Roofsm..
Mastering IC's is just as hard as mastering fox, desynch has alot potencial, even that the CG's seems easy, getting the grab on a jumping opponent is kinda hard, you'll need to space like a marthplayer, with shorter grabs and smashes. Wobbling is very situational and risky, if you don't manage to do it, you've lost one key of winning the match, an oppoturnity(wrongly spelled) to CG!
There's even ways to counter wobbling, like playing D-smashhappy peach(dair to nair can be annoying too) or CP stages like mute city to brake the wobble (If theres one stage I don't like meeting shiek, it must be this one)
Shouldn't Helios have tried picking up IC's against Ek and win a tournament with them if it's so easy....
