PsychoMidget, those tourney matches are amazing. Uair to up-B to uair surprised me, wish I'd thought of it.
I don't have easy access to Brawl right now, so could I ask you to test something for me? Try landing a down-B on your opponent. I think you have to be in the air and on top of them, rest style, but I know it's possible and I'd like to know the applicability. Maybe air-dodge to down-B?
As for this thread, I noticed some stuff in the down-B section. It detonates after a set amount of time automatically, and it can only be detonated with down-B, not just any B move. You can down-B in the air, both to lay and to donate, and when you lay it, it falls straight down with no momentum.
Also, if you're hit while holding a grenade, Snake drops it immediately. Stupid Pit arrows.
