Jason Wonders (VP of Advertising at Visionary)told me that they don't soak up as much oil as other balls, aren't as porous, and can last without resurface or rejuvenation for many times over normal modern balls. He said he had a gladiator solid untouched for 500 games and still reacts the same. Told me this when asking how to take care of them compared to my old arsenal of Storm balls.
I have had my set of 6 Visionary balls for a month now, I bowl 10-15 games a day. They are doing great, and I have noticed multiple things about how much durable they are than my Storm balls were. First they don't seem to really scratch as easily. Also there's a ball return in the alley I bowl at that always put little dings and scraps into my Storm balls. They were really bad, every shot you could see it. Well with my Ogre Solid on that lane 3 games in league, the dings were very very light, and hardly any on the ball. So that seemed to prove something totally more durable with the coverstock than any of my Storm balls. Every one of my storm balls on that lane I've used look terrible after just one game and still have the marks even after 3-4 resurfaces. I can't really easily find them on my Orange Ogre, have to look real hard and there are only a few.
So I have seen this same thing, they definitely are way more durable. Not sure if it's that they are harder or more flexible, or more elastic, better composition and don't dent cause of that. I also swear they don't cause the lane to break down as fast either, I'm guessing cause of the non-oil-soaking qualities of them. I can play a line way longer with them than my Storm balls could ever handle doing.
