Ex Sand Grenade for the launcher or the plus frames on block. Other than that EX Sand Trap, EX Slide, or EX Sand Toss(Outlaw) for getting out of pressure/waking-up.
You should really save your meter on breakers though.
-EX db4 in outlaw (sand throw) is a great armored combo-starting move to use on read or as an anti-air
-EX dbf2 (sand trap) is an armored command grab with longer range than sand throw that will net you 13% if it connects
-Meter burn dbf2 if you think the extra shot will kill your opponent
-EX bf3 is a good way to make your mixups plus on block or full combo on hit
Thanks for the help everyone. Does anyone know the best combo off of a raw ex sand grenade? Also, randomly, the best combo off of a neutral jump punch?
