ok I've just been for a lap around an industrial area close to mine...I can launch fine at ~5500-6000rpm without LC, just have to rev blip to there, let go, while revs starting to go down(like a split second), release clutch to bite point, smash accel and completely release clutch simultaneously/quickly... don't get any wheel spin but, so I'm assuming I'm doing it well...launches great like that.

Practice this weekend
