I was initially taught the Franco=Belgian hold in fourth grade, but in high school my orchestra director taught me the Russian bow hold. After I picked it up again as an adult my teacher re-taught me the Russian bow hold (I had to re learn it), and I have always felt more secure with the Russian hold. With the Franco-Belgian hold I always felt as though I was going to drop my bow. It’s hard to say that one is better than the other; I think they both have advantages and disadvantages. Knowing how well my past teachers have played with the Russian, I can’t say there’s a real downside to it though.
