I'll normally try and crimp the lip of most pokets if I can't get into it's juggy depths. Are we talking about holds that are so small or without a high bit to get into, so you can't tripod (I've ben told this is called a hock-stack).
So after cramming, crimping and stacking, my fourth instinct with such a pocket is to see if my pink tricam fits in it, and if none of those work I'm going home.
