Just drilled up my Avalanche Pearl today. Not so much a straighter ball as everyone has stated here. I expected a few more boards out of it than my Power Groove. Pin 4 1/2 from my PAP and CG 4 3/4 from PAP w/ the pin under my ring finger. The ball is very smooth and hits great! BUT for anyone looking for a ball to go fairly straight, go ahead and get a Power Groove. This may be different for others. I love the roll and I know I will be using my pearl and solid a lot.
