My biggest win so far using fox....hmmmm. Probably someone in my crew whos roughly as good as me, techchase, and the 1 game I took from Coney with him. Still, I've only used fox in 2 tourneys so far since being back with him, and I didn't go pure fox in those tourneys either(I don't plan to in the future, but regardless).
I was ranked 10th over the summer with Falco. Honorable mention when I used Fox Falco(Only used fox for one tourney that season, and I only made 3 tourneys that season; so I barely had any results to justify a good rank xD).
I got 2 more tourneys I plan to attend in the next couple months; so we'll have to see how those go.
Robfox you should really go to Br3; its going to be good, trust me.
