Rhino76, on the topic of shooters...  1.  pin above ring, cg in the palm, almost straight up MB drilled out in the thumb (dull or polished this worked, good read and backend).  2.  Pin below the ring, cg to the left of the palm, a negative drilling, MB in the track.  (works great on flippy lanes where the back end is too much for the Killer Instinct, doesn't over react).  3.  Regular leverage drill.  MB in the lower left quadrant (good ball for a little less hook than the KI pearl, but more backend than shooter #1.  #4.  315 danny wiseman drill, drilling is OK, I have the V2 sanded with this drill and its great, in the shooter it's OK.  VERY condition specific, like bowling the TAT or tough over under pattern.

Hope that helps
