Well the counting fingers, finger through palm and noseplug R.C.s have worked for me 100% of the time...... on the single occasion I ever used them. So I wouldn't have any idea what ones seems like they work well for me or not, apart from those three.

I guess the noseplug worked very well, as it was tactile and not visual, which can be an issue in some dreams, where you can't really see your hands that well and you don't notice your fingers.
