I have to agree with what has already been said, the Viscious line is all skid-flip. The Original Viscious like to roll for 50 feet before making a straight left turn, as did the pearl. The Viscious Particle, while more arc shaped than the other two, still flips hard for a particle ball. Skid-flip is what the Viscious line is all about.
As far as the Blades are concerned, I wouldn't say that they are skid-flip either. The Pearl gets good length and gives strong backend, but it's more of a mean arc than a snap. The solid blade rolls earlier and arcs hard on the back as well. If skid-flip is what you want, go with the Viscious balls. However, for my money and sanity, you'd probably be better off with one of the Blades. They hit just as hard and are much easier to control.

Bowling is without a doubt the dumbest, most pointless, most idiotic excuse for a game that has ever been invented. So, what time are we bowling tomorrow?
