Thanks for all this guys, been doing tons of research on all the links and types of pass you suggested.
Brandon's seems the most technical and logical to me.
I found some drills by Sean Bollinger in MTS episode 25: You Know How 10 Cruise.
These drills are at:
13:43 – Guard Passing Drill w/ Sean Bollinger
44:36 – Hand in the Back Pocket Guard Passing Drill
What I notice is that in sparring and matches Marcelo Garcia almost always uses the pass Sean shows at 44:36. The ones he shows on the DVDs and on his MGIA site he very rarely uses (couldn't find much footage at all, in fact). Strangely though, I couldn't find many videos of Marcelo actually teaching the drill at 44:36, despite seeming to use it primarily.
Just wondering why you guys think this might be. Is it because he thinks it is only for absolute elite people (i.e. a novice is likely to get swept as they attempt it), is it because they are dangerous, I'm not sure why he wouldn't teach his go-to move, that is all
