Two people who I've both seen do awesome things in person as a result of P5.
Firstly, if you've ever been to a P5 jam you will have seen Mole do something outrageous. The guy's too good.
Secondly, Bertie Buck is a guy I've known as a friend-of-a-friend for a while, although I did get to ride with him for a couple of P5 jams too. Another guy doing things his own way, but with a totally different style.
Didn't realise he was on Stolen either, but that's cool!
