I'm basically throwing all Storm right now, and I can tell you that most of their current line is top notch. I would suggest either a Lucid or a Frantic. I really feel like I can tackle just about anything with these two. If your house has weak backends, the Lucid would probably be the better call. It revs up nicely and just wrecks the pocket. The ball is stupid-good. The only negative to it for me is that it shines up super quick. Still, hit it with a cleaner and some abralon, and you're right back where you want to be.
The Frantic is also excellent. I find it best on mediums, but you can find use for it on heavy as long as the backends are clean. I fired an honor score the first night out with mine, and I didn't put it down for three months thereafter. It's just a great all-around ball.
I don't think you can go wrong with either. Really, everything I have from Storm - Vivid, Lucid, Mod. Marvel, Frantic, IQ Tour Pearl, and Crossroad - is really good. It's just a matter of what you're looking for in terms of shot shape and conditions.
