Good job, I recently watched this vid from a Gymkhana event down here in NZ
My big bike is a twin but it handles the rear brake / throttle thing ok. A quick dab of clutch & lift the revs when I get chain slap. Turning on a camber? Oh, it's freaky. Part of our course is on a downhill road 5 mtrs wide, the first few attempts I was really tense & muscling the bikes around a bit at a time but turning to look over my shoulder for the next point & putting my body inside the turn eventually relaxed me. Like you say, if you look at your feet or front wheel that's were your going.
