James speaks the truth, best advice every time this question comes up. I paid and waited for one of these high end bows that I never laid eyes on outside of the digital world that has been mentioned numerous times in this thread. Waited 12 months for it. Had it for a few months and sold it. Don't get me wrong the bow was what everyone is looking for, but it just had little things that I didn't like and I could tell it was always going to be collecting dust. If I would have held and shot it first I would have saved myself a lot of time.
I currently own a Morrison Cheyenne, a Shafer Silvertip, a BW PSAIII and a Whisperstik MojoStik and none of them will ever leave.
Try before you buy...Most of the top end bowyers will mail you one to try.
