The Solid Uranium for some reason seems to cause some people's tracks to get a little funky. For me it works out great because my track actually inverts a little when I throw this ball, which is a little strange for my normal PAP of ->5 ^1/2.
I have scored consistently better with this ball than any other I have ever owned, and I actually think the track inversion has a little something to do with it. I can't explain why this happens because I don't totally understand it.
The best I can do is tell you that this topic has been discussed quite a bit on this forum in the past, and you may have to go back a ways, but if you can search back far enough on the Solid Uranium, you'll find some pretty good discussions about it.
