No, I don't. All I can say is that if you need something for the old Newberry line, you have to try to reach them through HCA. I'm a little peeved with Richard and Newberry at this point and doubt I buy anymore from them. Since he bought HCA I feel he's snubbed the old Newberry shooters. I've called and emailed with no results. I called HCA to ask for some heavier limbs for a Newberry Spike and got the old "he'll call you back" after he sees if he has any. Many months later - no call. No answer to more emails and no answer to more calls at HCA. Unless you're interested in his new company, you don't seem to matter. I love my SB1 too and really liked how Newberry/Archery Pro treated me as a customer, but that is no more. I was told, however, that the Newberry line was just "on hold" until HCA got on its feet, but I see Newberry models getting incorporated into the HCA line. We'll see if it all sorts itself out, but at this point, I'm going to shoot the limbs off this SB1 and then look elsewhere. I"ll probably be totally trad by that point anyway...
