My number one bow is a HCA carbon 4 runner, I have shot numerous "NEW" bows and liked most of them. A select few shot as well as my 4 runner and none of them were as light!! Until something disasterous happens to my carbon 4 runner, I just can't justify spending all that money for a "NEW" bow. If HCA started building carbon 4 runner bows again, I would buy one in a minute. I think it is a valid question you have and sorry I dont have an answer for you, but like you, I am a fan of carbon bows!!
