Great thread! Can't say why it works but it does. I have 3 main bows, listed below I think. Anyway, when I'm frustrated with one, I'll shoot with a different for a while. No particular order. My R/D Bamabow is my main one. But I'll grab the selfbow sometimes because it gives me a great site picture. And the Samick Sage recurve has a nice grip. Dusted the Sage off the other night cause its the only Take Down I have and I had to pack one for the TBOF, so I tied on some nocks and was zinging them right on target after 15 shots or so. But I can agree that I think it has something with improving your focus and form, where each bow will force you to do something different to shoot well, and all of it equals to better overall form and success.
