I only know one and he's the one that taught me the Dan Brown method.
He's also the one that stole a cube from wal-mart and sold it to me for 2 bucks
However, being me, I usually get really serious and into things that I like to do in my free time.
I started actually speed cube a month and a half ago and I'm 25 sec average now, I'm way faster than him. He refers to me as "pro"
I also had a cuber at my other school last year, but he was barely sub 1 minute and there are cube clubs here in Vegas, however they're all sub 40, none are really sub 30. (That I know of)
