What I'm looking for here is a ball that can handle heavier/longer patterns when I square up.  I don't need to cross 30 boards on those conditions.  I'm looking for it to be above my 5.0 and Roto Epic, with a bit less backend.  The drills on the 5.0 and Epic are identical, with the pins below the ring finger, mass bias in the strong position, and weight holes in the thumb positive quadrant.  Both are wonderful balls, but they really turn hard on the back.  The Epic is great when the 5.0 won't quite turn the corner, or comes in behind the headpin to leave me 10 pins.  My last measured PAP was 5 1/8 over and 3/16 up.  I'm a medium track tweener with about 17 MPH ball speed.  

I'm not sure what the top on the GP2 is, and it's getting plugged now.  It's about a 2.5" pin.  I've got a couple ideas, but I wanted to hear from the guys that know this ball before I make a decision.  I can also do cover adjustments.  If I were to use the same drill again, am I correct in assuming that the GP2 would start quite a bit earlier, but still have a strong arcing backend due to the dual particle?
