In a perfect world, where MK 9's online experience was like TTT2's; I'd take you up on this in a heartbeat.
Unfortunately, the MK 9 online is so ass that it wouldn't really work to train for the instant / delayed 3's. Sorry, dude, but my disdain for online is massive. lol....it's good for learning basic match-up's data. But once you get that down, it does nothing but forces you to spend more time getting OFFLINE experience because you become so attuned to how to play online.
Granted, a lot of people are forced to only use online due to lack of local scene. But if you keep going to events like you're going to at MLG, you'll begin to understand just exactly what I'm talking about. /rant
So when you get there to MLG, don't be afraid to ask some of the guys what to do here, what to do there, etc.... Especially Brady. Ask him about what he does for instant / delayed teleport 3 and if he reads them or if he actually REACTS to them. He is nice and a very good teacher when you talk to him in-person.
