I have an Avalanche Pearl drilled up with the Pin 5' from my PAP and the CG in the center of the grip. The ball is awesome on short patterns like Cheetah. It is very clean through the front and makes a hard, continuous turn to the pocket. I have seen the Slide, haven't drilled the slide yet, probably will to complement the Pearl. I've seen it thrown by a friend how is a good bowler. I've observed that it is at least as clean as the Pearl with stronger motion on the backend. I'm concerned that on the same short pattern (Cheetah), it may be too much on the back. Maybe a go to ball when he shot starts to break down a bit and the Pearl starts to lose the break point. If/when I drill it I'll probably set it up similar to my Pearl so as to compliment it. Bottom line...I would not hesitate to drill the Pearl for what you are describing it is a great piece.
