Picked this ball up last Friday.  It is drilled with the pin 4 1/2" from my pap and almost touching the right side of the ring finger.  Only threw it a few frames to get the thumb hole right.  Then bowled in league on Monday (3 games) so this is a short review.

First the ball gets great length on a house shot.  Second when it turns on the back end it's very angular and finished harder than any of my other equipment.  It carried both light and flush hits very well.  Even when I missed a little right, the ball had no problem coming back to the pocket.  However, a miss left and you're in a heap of trouble unless there's a lot of oil in the middle.  I don't know how the other Rival's are, but this ball looks like it will be a winner.  

I'll post more after a few more games.
