If you are serious about playing melty, I think this is a great move for you guys. I think you will learn a lot about the game, and about your own play.
If you are going with the intention of being competitors, well, that's another matter. I've never seen Ruu or Mint play melty, but from what I hear about evo, our best GG players aren't any where close to them. Having played with Veteru, who I think it probably right at your level, if not maybe a little under, I can safely say that I think you're making some oversights. There are going to be a lot of matchups that you guys probably havn't experienced. How many people in the US play their characters at the level you play yours? Have you ever fought an equal quality Ciel? Warc? Wara? It's one thing to know their mixup from videos and another to be actually blocking it. I'm making that assumption based on the vids I've seen online, so sorry if it's off.
Any way, I'll offer to get you guys dinner some where tasty one of the nights you're in Tokyo. I've been wanting to meet/play you guys for a while.
