Forgive me if this topic has been covered before, but I did a search and couldn't find it. A couple of weeks ago, I had a lesson with my teacher, and he wanted me to take a shot at the old "Stick O' Pain". Since I don't own one (and didn't really want to for many reasons), he brought me an old one of his and left it with me to use indefinitely. Anyway, the bow he brought is a French bow, and we worked on the grip and getting a good sound with the bow. All was good, but the more I try to practice with it, the more I have this nagging feeling that the French grip is not for me - it puts a very unnatural torque on my right shoulder, especially when playing on the G string. I tried holding the bow in the German fashion, and even though the grip is all wrong, I was able to get a good sound much more easily, and my shoulders immediately felt more comfortable. This leads me to believe that I may just be a "German grip" type person by nature. The question is, how is this decision of which grip/bow to use normally made? What are the factors involved besides "my teacher played French, so I did too"? Thanks in advance, and feel free to rag me mercilessly if it amuses you.
