I know that, he probably didn't like the sound or feel and then went back to wood. He used the 11.75 revo which isn't a good option in my opinion a CF should be 12.4+ to have the affect of perfecting your timing and improving your gameplay automatically.
The thing with Kaci, he went back to wood and will remain at that level forever, because he did not like the sound or feel....it's his loss - he's a great champion though, lots of champions still use wood and thats fine, they will win at some points in life but they will not dominate.
Domination will remain in the hands of pro's that are as skilled as the wood users above but did switch and love their CF, the likes of Filler, Fedor, Yapp and Shane....the list is long but ill stop here. - I'd also like to mention Yapp's game jumped to a whole different level with his new 12.6mm Universal CF which is an absolutely insane shaft, ive tried it myself.
