I could go down a long list of bows I've owned and shot (as most on here can). I won't bore with details but there aren't many that I haven't tried, especially recurves. I've heard of this phenomenon many times and I can honestly say I've alway regarded it as hype. I've had some that, as mentioned, had a very smooth draw (like the silvertip) and that makes a difference.
Just two days ago my Dryad Orion recurve arrived and it is the first I've owned to feel like it draws less weight. I mean it. Mike called before it shipped and we discussed weight as he was doing final sanding. It came out 50@28" and feels almost just like my (very expensive high quality - name omitted) 45# recurve. I believe it is the static tips that lend a smooth and stack free draw, I dunno. I PM'd Mike yesterday to tell him this same thing. Now I'm a believer.
