LT I do not have as much experience as you in fact my experience is quite limited. I have only bowled in a few tournaments that had PBA conditions on the lanes and 2 of them were pattern C and the other was the US Open condition. I had an easier time with the US open than the C patern. The C was very over/under for me that is why I have been trying to change the way I release the ball to more of a WRW style, cutting back the side rotation and gaining control of the midlane. I have found that if thrown properly this shot will react the same on most conditions, my problem is throwing it consistantly with enough power to carry the corner pins.
My point in the begining was that Walter Ray is Bowling's Tiger Woods, or as close as Bowling will get, others disagreed, I was playing devil's advocate by saying maybe there is someone else out there that is "tiger proofed" by the current lane conditions of the PBA. Meaning no Disrespect to WRW.
I do know that I can not remember WRW winning a Tournament on TV playing a deep inside angle and covering many boards, I am not saying that he has not bowled that way all week and then got on the show and changed back to the end over end shot, because I'm sure he has done that. Last year he was hooking the ball from inside the 4th arrow and made it past one round on TV, but got beat the next game. The rest of the time I don't remember him bowling inside the 3rd arrow.
