Everyone's definition of a "super" cover is probably different, but I will provide my take.
I have thrown Storm, including most recently the Zero Gravity, Optimus Solid, Loco Solid (yes, Roto, but essentially the same), IQ Tour Nano, and a few others. I also currently have every VBP ball in production and many of the discontinued balls as well. WHat I can tell you is if you are looking for a super absorbant cover that sucks in oil and then needs revived in 30 games, VBP does not do this. Jason put his most aggressive shell to date on the Spartan and even then the ball does not suck oil like Storm's (or pretty much any other company).
With VBP, you get durability. I am using a Frankie May Gryphon as my go to ball right now that was poured in 2005....12 years old, many games, my speed is over 18 and it still turns the corner and hits like it was brand new. I do regular cleaning on the ball of course.
With Storm, the first thing I noticed is the ball takes tons of lane shine if the ball is dull and there is quickly a track. With VBP, the ball shines a little and there is little to no tracking. The covers hold up much better.
A note on VBP (Visionary Bowling Products) stuff...I use tons of blems....Jason and the VBP crew are VERY picky about what is marked as a first. Many of the balls that you see from other companies that are weird looking pours compared to the rest of the balls or has a ton of phasing will get released most of the time as a 1st from the other companies. Not at VBP. Jason and his crew inspects every ball on the line and if everything doesn't meet their high standards, it is marked as a blem. Tons of good deals to be found for slightly cheaper price.
Jason is second to none with customer service. Great guy to work with to answer pretty much any question you may have.
