They way the THS are set up, it's hard to think anyone can play up 5 with medium cover balls, one with Lower RG, and somewhat early roll layout. But, a buddy of mine does this and has averaged 215+ bowling up 5 at two different houses with two different lane surfaces. He doesn't throw like Eugene, but in the average speed range. I'm 16.5-17 at the pin deck and I roll faster than he does.
If I were to play up 5, I'd be using my breeze with higher grit or my spare ball. But my buddy can manipulate his game to play this area and camp out. AND, without seeing a paper coach...we call him mini WRW lol
