Yeah, I WONT deal with HK and there "@#$% the customer " outlook on buisness, and have never dealt with AMR, which id rather them than HK. For the extra $80 id rather go your route. As for the Bowman rings, I usually break my engines in on Franks rings. Some say they dont see a difference, i say they dont know what there looking at. I certainly see the difference. Ill check out the CRRC. Thanks
