Drilled under ring finger does have weight hole 4 1/4 to pap, ball does get very good length and is more of a backending ball. I also let another person with more tilt and revs use it with not much of a reaction difference, ball clears head well and retains for the back part of the lane on the lane condition i used it on.
The ball did not like carrydown and is weaker than original inferno and intense inferno balls with similar drills, i had best reaction with a dirty bomb pearl which is easily a stronger earlier rolling ball. It did rev up very easily and i believe without the carrydown it will be a great medium condition ball, my driller told me he watched alot of high end players using this ball at the mini eliminator. Most were getting alot of length and backend similar to what me and my friend were getting reaction wise, so i have not used it enough to say for sure it hates carrydown but my intial feelings is that it does with my drilling.
So i will report back next week or so about the carrydown problem maybe take it too 2000 abralon smooth or just knock down the shiny surface slightly first. That might take care of the carrydown problem and hopefully does not kill the built in backend of this ball which is massive.
