hmm. i'm not really sure. i dont really play him extensively. I played him earlier this week and I did alot better than I usually would do and almost beat him, then we disc'd so we only played like 2 matches, 1 of which was a ditto.
He's pretty good; his choke game is REALLY good and he's able to do pretty well in tourneys as far as I could tell. I dunno if he's Kalm or Swoops level or anything, though.
here's his youtube if you wanna look at some vids. There's a big one of him vs me from a few months ago(i 3 stock him once because he was being stupid <_<)
