I believe that the last time that Matt came to a contest was in 2008 when he was a judge at worlds. He was dominant in his time, a three-time world champ. But then he got into a band, soon got married, had a child . . .
The state of the art has improved dramatically since that time. Matt did crazy tricks, but always used bearing tops. Freestyles nowadays are mostly done with fixed-tip tops.
He was around 22 at the time, so he would be about 36 now.
Few of the players of the US spintop scene at that time are still active: Mark Hayward, Chris Neff, Mike Hout, Jon Gates, myself . . .
