Here's a pretty good video showing some techniques for more advanced players. It gives strategies for implementing some reset mix-ups into his game. The end is pretty funny too, just don't take it too serious Guy players!
Thanks to Valkyrie for the tip. Spotted on Shadowloo.com. This video was created by Goodpart. Great work! We have added a link to this video on Guy's strategy page for IPW's Super Street Fighter 4 guide.
