If they are all "in stroke" and at their best, I like Shane, Efren, Alex, Busti and Scott. Close behind are Gabe, Darren, Jeremy, Schmidt, Corey, Joey Gray, Chris Gentile and Sylver. The rising star in One Pocket will be Dennis Orcollo. Give him a year and look out!
You left out one that just beat Gentile, and will beat most of the second tier players you named, Cliff Joyner.
