Recently, I purchased a Jolt Pearl by fellow ballreviews.com member 5150BWLR.  The ball looked basically brand new.  Got it plugged, brought it to 4000 Abralon with Magic Shine polish.  Then my ball driller dude and I worked out a layout for the ball.  The goal:  to fit in between my Pyro and my Natural.  We chose a 50*/4.5 pin to PAP/50* layout.  This put the pin in my ring finger, and the CG a bit under my midline.  Something like this...P = Pin and C = CG

---o-P--                  
--------
--------
-----C--
----o---

This ball gave me exactly what I wanted...good length but a pretty tame backend motion.  It's continuous, but far from the snap my Pyro has.  Very controllable, smooth as butter, and so far the carry was excellent.  I look forward to trying this on burnt up sloppy stuff I see on my 2nd shift league tomorrow.  More to report then!
