I will say this, IMO the most skid flip ball I have had was the anarchy...BUT i was one of the few who had success with the "origin" core, thus owning 3 invasions....and finally getting an anarchy the ball just skidded all the way down the lane....and as soon as it hit the dry it was extremely uncontrollable..it was just a straight flip like I have never seen...aaaand i got rid of it!
I believe the "most" skid flip ball is going to be VERY relative bowler to bowler....because I am sure that a few people thought their anarchies were not so flippy but maybe rolly. Thats the beauty of the sport, everyones game is like a signature, everyone will be different. I would assume get something with all pearl in it, and have your pro shop lay the ball out to give you the most skid/flip reaction that fits for your game, speed, and revs.
Thats all I have...good luck
Don't throw strikes, throw BOLTS!
