I threw both the evolve and the jigsaw at the Powerhouse Challenge. Although I liked how the evolve rolled, the jigsaw, for me, was worlds better.
I think its just one of those balls that you have to match up with...some people do and some people don't. I guess I matched up perfectly with it. Its like a magnet to the pocket and gives me a good amount of area to play with. It carries better than anything I have.
Mine is drilled pin up, 4 1/2 pin - pap. The house I regularly bowl at is VERY slick and inconsistent at times, and the jigsaw still makes the corner nice and hard.
Hope this helps
