I'd choose the xxcel over the triple xl for it's carry down on the med-oily. They have the same back end reaction it's just how they get there. I hear a lot of good things about The One, but I won't get mine in the mail until tomorrow. I also hear a lot of good things about Lane#1's Hyrbrid Dirty Bomb. In selecting a ball, don't forget to take into consideration your own style, the ball should compliment it. If you're a stroker like me then I don't think you want something with late reaction and a strong angular back end. In my case I'm better off with something that revs early and has a smooth heavy rolling arc. For slower bowlers I'd suggest Apex Obsession for heavy oil or it's stronger hooking baby brother Over Time for Medium oil. If you have higher ball speed and revs (cranker) I'd suggest one of my earlier recommendations. JMO of course.

Look for me in the upcoming PBA Tour! I'll be the guy in the back row with the foam finger singing "Take Me Out To The Ball Game" during the 7th inning.
