Grips on German bows - why?

[Calvin Marks]

Good question but you wouldn't be able to just slap on a different frog without altering the camber of the stick, which for a French to German conversion would be fairly drastic (or visa versa). I play both bows and don't use a grip or winding on EITHER...Yes, not even on a French bow. I find that they mute the stick and stop vibrations. Rubber tubing for a French bow is also not the greatest idea as you can develop some poor technique habits.
