Many bows (especially pernambuco) can warp when you don’t ease the tension off the bow when you put it away. Make sure you see dangle in the hair when you put it away, especially if you are in a high humid area. All it takes is one time, and the stick will bend (warp) which will totally ruin the bow if left too tight in an over-night situation. Carbon fiber bows on the other hand are much better for this type of situation. They are very durable and won’t warp like a delicate wood bow. This doesn’t mean you should go with carbon fiber, unless you really think you won’t be able to take care of your pernambuco bow.
