I've never seen Tim's striking as well. His throwing, though, is way impressive. He gets serious air off his no-gi throws. And it's all Bagua! I trained with him once and he told me he once threw a guy in a no-gi tournament so hard the guy rolled all the way over and landed on his knees- and got awarded no points. If you look at his throws from a wrestling perspective, he uses a lot of snatch singles, trips and knee taps.
His BJJ is also very solid. His guard game is similar to what Mike Jen shows on his tapes. Climbing guard, a lot of redirection. He was tapping me every minute or so (I'm a blue belt under Roger Gracie. I was a white belt then, but I think he was being nice.).
Tim has won a few Copa Pacificas Master's at different belt levels. He's won a superfight at Copa Pacifica as well. If I recall correctly, he fought at Mundials, but I don't know how well he did.
You can check out his website at www.shenwu.com. A few clips of his BJJ fights.
And he's a nice guy! :)
