If you want roll, then out the pin closer to your PAP.  Instead of the recommended 4" x 2", I suggest a 2 3/4" x 2".  

The flare potential is roughly the same (4" - 3 3/8" = 3 3/8" - 2 3/4"), but you are using the lower RG.  

I have balls with both of these drills.  For me, the 4" x 2" generally has good length with a stable breakpoint, but on heavy & long it can still flip hard if the backends are strong or stake on me if the backends are wet.  The 2 3/4" x 2" generally has a steady movement.  On the heavy & long, it doesn't overreact on dry or stake on carrydown, but when the heads go I put the ball back in the bag.
