I have one with the pin under the RG and the CG kick out 1 inch from the center line.  I keep mine at 1000 abralon finish.  The cover is mild for a solid reactive, but reads the mid lane and break point very consistently.  Heavy rolling, hard hitting, and very predictable.  No over under.  A true bench mark ball that got very little love from the Lane Masters nation.  I got 1 300 out of my XSP so far and flirted with two more . . .

i am getting mine drilled as we speak. Going pin up 5 1/2 x 5. Don't know what to expect. I was afraid to drill it to strong with the high dif and low RG. If i still flare around 4.5-5 inches I should be alright.
