I was just looking at the Lane #1 web site. I noticed they've made a drastic change to their hook ratings. And I think it's for the better, since 6 out of their current 8 were 23-25 while the truth was the characteristics were not well defined by that rating. Now they're giving 2 ratings per ball, total hook and backend hook %.

Super Carbide Bomb    120  50%
Uranium Solid         100  60%
Black Cherry Bomb     90   75%
Uranium               85   75%  
Cherry Bomb           80   70%  
Golden Nugget         75   80%
Bullet                50   55%
XXXL                  30   50%

I think it's a great new rating system, it does a much better job of showing total hook and ball reactions.
