For no-gi, which tends to be more MMA oriented in my case, I use can openers and a double underhook pass alot. I also stand up and pass the guard, which is my second best pass behind the can opener.
For gi grappling, the toreando pass is my go-to move, though I also use the double-underhook pass and the traditional pass (Jeff Monson calls it a "jailbreak pass").
If you want a walkthrough of any of those, I'm glad to give you one.
Nice to see that the can opener -> double underhook pass works well at high levels. I started experimenting with that last class and had good results, but wasn't sure if it'd hold up against better grapplers.
