I think Rick should re-watch the show, the radical that Loschetter was using on tv was burning up so bad that it was dead on arrival, that is why he switched back to the zc, I was impressed by at how quickly Loschetter realized this and made the change right away.
Now if the Radical surface change Rick described on the website, makes the ball hook more on the back end, then I agree with him that Chris should have switched to that one, but there was no video or good description of the reaction differences between the 500 grit abralon or the one with the emery cloth, so I'm not sure if the reaction difference was at the front or back of the lane.
Imo Chris would have been better off with another radical with less surface, unless less surface = less backend. I had an addrenaline that was this way, the more I shined it the less it would snap on the backend, maybe the Radical is like that.
If anyone knows please chime in.
