Abe* ought to be able to tell you, he's building it. South Cox at Stalker Stickbow would also have insight. Or maybe Roman at Hill Country bows. I believe the word is from what other TGers have said, it affects it a small bit, but nothing silly, what's a couple feet per second? Some say it doesnt affect it at all. Most people are thrilled with the beautiful look of that wood enough not to care about 2-3fps, if its even that. Hope someone who owns one will reply for you. Email South, very nice guy.
