Hi Eddie,
We are working on developing a new hook rating system. The problems that we are facing with the old rating system is that each bowling style rates the balls differently, and when you average them out, some of the balls come out almost identical.
For example, when a cranker throws something like the Green Gargoyle (pearlized reactive) on a medium house condition with fresh backends, it can absolutely fly across the lane. For myself (i turn the ball a fair amount), I can go gutter to gutter, and I would call the overall hook rating on this condition a 90/100, and the backend 95/100. When a stroker throws the ball, they wouldn't get nearly the same amount of pop on the backend, so the overall hook would be less and they may rate the overall hook rating at 75/100 and the backends at 80/100. Average it out, and it becomes 83/100 for overall hook, and 88/100 for backend.
Now, throw a particle on the same lane condition, and while it hooks much earlier for me, it bleeds off alot more energy during the front portion of the lane where there is oil, and doesn't have much left on the backend. I may call the overall hook on this condition 85/100 and the backend 80/100. When the stroker throws the ball, his low rev rate will allow the ball to retain some of it's energy, so he gets bigger backends and more overall hook. He might rate it as 88/100 for overall hook, and 92/100 for the backends. Averaged out between the two styles, and this particle ball now has an overall hook rating of 86/100 for overall hook and 86/100 for backends.
Comparing the two, you get the following:
Pearl Reactive ball - overall 83/100 backend - 88/100
Particle ball - overall hook 86/100 backend - 86/100
Even though we both rated the balls completely different because of our styles, the averages ended up being pretty close to the same. If a cranker purchases both of these balls, and thinks he is only going to see 2 points difference in backend, he will be disappointed when the particle ball doesn't have even close to the same backends.
Vice Versa, if a stroker buys them both, he would be disappointed that the skid/snap ball doesn't come close to the same amount of overall hook.
As I said earlier, we are working on a new method of comparing the balls, and we should have it ready by the time we release the catalog in June.
