Why not adjust the bias and try NO hand on either. Get that boot centered! WARNING....this can get pretty finicky! But theoretically due to sidecut to center the boot between the edges you need to run some bias. Plenty of people don't bother, but maybe it'll suit you.
Maybe this is actually the source of your problem? Twisting won't get you anywhere but busted up, imo, so maybe (not discounting setup problems here, but...) you need to have a look at your technique, too.
I don't think anyone would suggest ever initiating a turn by only leaning into it (except when practicing the norm)
Good to know! As long as you've got the right positioning, and are able to carve "feet up" you should adapt to higher angles in no time!
Definitely try a wider stance, but not TOO wide. Also try riding completely flat? Some people do it! Or ALL lift, no cant, or, or or or orrrrrrrrrrr (welcome to the geeky world of carving equipment!)
