I played a bow in a local shop recently that was a very nice overall bow. The weight and feel was wonderful, and it was very easy to play. A nice octagonal permanbuco stick, French. It was very modestly priced, and overall, seemed better made and certainly played better, than some others demanding a higher price. Then I noticed that with the hair tensed, the bow was not straight. It kicks out to one side ever so slightly. With the hair loose, you can hardly even tell it, but with tension, you can see it. It isn't twisting. The hair seems to stay on one plane under tension. It's just slightly bent. I can't tell it at all when playing it. I'm not sure anyone could unless they were particularly in tune with their bowing. It is otherwise so nice and easy to play, that I am considering buying it anyway, especially if I can get it at an even better price. So my questions are, if I buy it: 1. Should I expect this condition to worsen overtime? 2. Can this be corrected? 3. Are there any other compelling reasons to avoid this bow? Right now I have a nice Pernambuco bow that I just bought, and I still have my Brazilwood bow, but this one was really nice. I liked it very much.
