Looking for a pearl ball to fill out my arsenal. Heard great things about all 3 of these balls. Current arsenal is  IQ Nano 1000   IQ Nano 4000 polish    IQ Tour oob  Hyroad oob and a Ride. I feel i am missing a true skid flip ball. Had the Lock but just didn't work well for me. I know the Snap Lock is suppose to really boom on the back end but want to try and stay away from the Lock. Missing something between my Hyroad and my Ride. Too big of a gap in my opinion. Also considering the IQ 30 since I already have 3 IQ s . Radical Jackpot looks like the real deal too.  Appreciate the opinions.

Hy-Road Pearl is my vote as it does just what you described you need. That middle roll core in the Hy-Wire will give a smoother reaction than you're looking to achieve in my opinion, not that it won't still make a good move on the backend. No experience with the Jackpot.

If you're considering a Radical then the Ridiculous Pearl is probably the way to go.

For Storm I agree with billdozer that the Sky Rocket fits the bill. So does the Hy-Road Pearl of course, but it gets boring recommending that ball so much.

Not sure anything in the current Roto Grip lineup does though. The Hy-Wire might, but I've heard some say it's really skid-flip for them (in a good way) and others have it as a tamer reaction.
