Jamie, that's exactly what I've heard, and why I bought some to try. I've never had 'a problem' with how my bows shoot with B-50, with creep, stretch, duability, speed, or the feel at the shot... BUT if in the end I prefer D97, if only because of how it feels at the shot, that's reason enough for me to switch string material.
I admit, I've been hesitant to try a low stretch material because I've heard many folks declare it would be detrimental to a wooden bow, and I'm not about to spend the time and effort on my bows that I do, only to have them ruined by the string. But lately I've heard more and more insist no damage will be done, so I'm willing to give it a shot.
