Probably Brian Valenta from Lockport, Illinois. Brian is a former member of Junior Team USA, a collegiate all-american when he bowled at Lindenwood University. And he's bowled very well before at the US Open finishing in the top 10 one year as an amateur. Recently he's been doing a fair share of PBA regional events, and he was PDW's doubles partner last year in the member/non member doubles.

There is one thing he can probably do better than all the other two handed bowlers before mentioned. He can play the extreme Maxium Bob Angles better than them, and he can launch the left gutter cap very well and score when it's deemed necessary.
