How do you make sure the cube doesn't rotate on you?

This is a significant challenge--not only keeping the cube from rotating out of control, but also throwing it in such a way that it does rotate into the orientation that you need it before making a move, or at least close enough for you to catch it that way. I have two pieces of advice for this:

1. Do moves only (or almost only) with your OH hand. If you're like most cubers, your OH hand is non-dominant for most purposes, like juggling, so this has the added advantage that the throws setting up each move are done with the steadier of your two throwing hands. I have managed to do a solve or two with all the moves done by my non-OH hand, but this is significantly harder. Also, one of the main difficulties of solving while juggling cube + ball in one hand (another thing I've tried a couple times but not completed yet) is that the strong OH hand tends to rotate the cube out of control, but the strong jugging hand has trouble doing moves.

2. Practice. It may help, for example, to practice just throwing the cube without rotating it, inspecting a cross while juggling, solving a cube in a 3-ball pattern but without the other two balls, or doing a PLL while juggling the cube with the balls. Also, using smaller juggling balls should help avoid collisions, which are always a significant concern when you can't concentrate fully on your throws. Don't start with three cubes, because then almost every collision you have will result in a drop.

I'd like to make a sort of cube-juggling tutorial some time, but my school year just started up and college does interfere a fair amount with such things. Maybe I'll have time one of these weekends though.

Thanks for the detailed reply.
I do OH and juggling with my right hand. I've had a few full solves of 2 ball juggling in my right hand, OH cubing in my left hand (I use right hand for OH but I'm pretty bad at 2 balls in my left hand, I can usually only last about 20 seconds, whereas I'm still a decent speed with my left hand, about 30)
I just can't stop myself spinning the cube slightly, however, I learnt mills mess a few days ago, and whilst I can't last too long, the cubes don't flip as often for some reason.
I've been having trouble with algorithm memory, because I don't usually solve with my left hand, and I don't watch the cube.
I'll keep practising until I can do 2 ball shower whilst solving with my slow hand consistently. And I'll work on mills mess because I find turning easier in mills mess, even though the pattern is harder.

Just so you know, your video made me start juggling, thanks!
