Been dabbling with Sonic a bit. Sonic is, of course, amazingly fast, but he doesn't have a whole lot of "oopmh." I've found that comboing from a spin dash into a Fair or Uair is a nice tactic that deals quite a nice bit of damage.

My only problem really is that for some godawful reason, I have about a quarter-second to half-second lag playing online, which makes timing anything a huge pain in the ass, particularly for a character like Sonic. I don't know what's going on, as anything I else I play has no lag whatsoever. I changed my wireless router's channel, forwarded every applicable port I could think of, but my ping seems to be in the orange no matter what I do... if this keeps up, I may have to give up on Online play.
