I actually only use one closed guard break. I get posture - grab an arm - and stand then just use gravity and a helping hand to break the guard.
Edit: Dealing with the collar grip is hard for me at times as in my gym guys just tend to let you open guard as we all prefer open guard. Means I need to concentrate at comps (+ guys grip harder at comps???). I've found you can actually stand even if they have the collar grip although you're in a more vulnerable position for sweeps and subs so ideally I'll strip it with a 2 on 1 grip on his wrist and good posture.
Pretty much all I use as well. I prefer a cross sleeve grip, but I'll take a same side grip if it's all I can get. You do need good grip strength to do this however...if they break your grip and you're standing without a sleeve grip getting swept is a real possibility.
I like the variation of a sau palo pass. I keep good posture, hand on the lapel. Good posture they can make the grips all they want and won't be able to pull you down. I then reach behind me and find the guys feed. Break his grips and start a stack pass. It's a little risky, but if you do it right the triangle is telegraphed and it's easy to stuff. Otherwise I do the basica knee in the butt guard break, or a variety of standing guard passes. Good posture is key.
posture... grab lapels with both hands... feed both into my right hand... grab his right sleeve with my left hand (same side)... punch it underneath my right arm and stand up with my left leg first... hips forward.... right knee in the middle and break...
