I've heard of DJ, and all of it good. Its awesome that he gets that kind of training in. Just thinking of the training I would get from that caliber of sparing partner is mind boggling. It would be like me training with AZ or ADHD on a regular basis, haha. That kind of spacing on Vex's part is kinda crazy though. Especially considering how fast a Metaknight ditto match can move. Tell DJ congrats for me. I'd do it myself, but it would be kind of awkward to message him out of the blue, especially considering that he doesn't know me.
You mentioning AZ makes me think of his matches with t0mmy. Crazy stuff. Don't give up though. I thought I would never reach a point in my playing ability where I would be able to beat him or t1mmy, and though its rare I can pull off the occasional win, even a two stock depending. I'm also rather glad they don't have to sand-bag me anymore, haha.
One more thing I forgot to mention about the tourney... ask M2K to show you his and DEHF's "special team tech" next time you see him. You'll get a few lols. And just in case you wonder when you see it, yes they did use it in a tournament match.
