15# 3.5-4 inch pin 3 oz top

Mine is drilled with a "modified" label drill because the pin to cg distance is so long. The pin is pretty far up and to right of my ring finger and the cg is just over the top and little bit to the right of my thumb.

I love this ball. It has a very nice controllable reaction and it  doesnt over-react when it hits the dry.  

Last week I shot a 230 in the first game with my Command Zone Arc and it would have been higher but in the tenth frame it just went straight and stoped hooking.  The whole second game i strugled in trying to find the pocket and in the tenth frame i took out the rsp and boom, i struck out. it ignored the carry down. finished with 167 in second game and a 257 in the third game with the RSP.

Ball Specs: 15#, 2 inch pin, unsure of TW as I bought it used.

Drill: Pin below and just offset outward from ring finger, cg roughly in center of grip
I don't know the specs regarding PAP for this drill, but my PAP is 4 over and 3/4 up.  If I had to guess I'd say it's about a 3-1/2 by 4 layout.

Surface: 500 abralon finished with Storm Step 2 Polish

Lanes: Wood with some carrydown from 1st shift women's league.

Reaction:  This piece gives me good length for those worn down heads.  I get a medium mid-lane read, and it doesn't overreact to dry at all.  When this ball makes its move off the breakpoint, it's a strong arc that pushes through carrydown and continues through the deck.  I really love the way this ball holds its reaction as the lanes transition.  I can get a good look on a swing shot, and if the track area burns up I can get a solid hold in the oil on an inside line.  The reaction is very controllable and predictable.

I haven't had a chance to throw this ball on a fresh shot yet, but I think the particle pearl cover should do a good job of smoothing over/under.  All in all, this ball is a great benchmark piece that sits well above my Sonic Boom.  

I give it a 9.75/10, couldn't ask for a better piece, especially at this price point.
