Well, I've always done OU - I'm fairly new.. But, I've been growing my UU collection, too. I could probably put a decent UU team together, but it wouldn't be that well thought out because it would have to be patched together with what I already have. But, I'd still love to try.
Yeah, I started playing 10 years ago too and had no idea that they still made Pokemon games until about a year and a half ago when my xbox 360 had the red ring of death and my room mate and I had nothing to do during Fall Break. haha
