We drilled this ball for a teammate with slower ball speed then revs.  She's a small person, using a big ball.  We picked this ball because she'd had great sucess with a Cuda 2000 that eventually seperated.  This ball has the same cover.  Though the Cuda we drilled label, we went a bit more with this one drilling it leverage.  We got away with out a weight hole.  And then we took it up to 1000 polish and kept it there with diligent attention.  

This ball is a very strong ball.  Its a good ball to give the bowler a nice snap at the end.  Especially if they bowl in the drier area of the lane.  The ball has a great continual drive, it doesn't quit.  Then has plenty of energy left to make an impact at the pins.  You need to really throw this one into the desert to get it to roll out.  And it's at it's best performance polished.  

Recently (due to lane condition changes) we put a weight hole in the ball as it was getting a bit unpredictable for the bowler.  Now its much more controllable and she's doing even better with it.  We still make sure its kept up to a high polish for her style.  

I would recommend this ball for all medium conditions.  And especially recommend this ball for those that want some strong reaction but don't necessarily have the physical ability to force that reaction in other equipment.
