I have a big problem with horse hair because it breaks a lot. It’s probably partially my fault because I like to produce a strong sound and I also play virtuoso programme a lot. That’s why I have to rehair my bow every month, sometimes even more. It is really expensive and takes a lot of time. Fortunately, if Coruss hair doesn’t break so easily (it didn’t break so far), I think I found a solution. I have to admit that I was little concerned about the sound quality but when I tried it I was positively surprised. It’s better than I expected! It produces solid sound immediately as I touch the strings. And the sound is pretty strong.
