For me I've found the the fewer number of teeth on the blade there is the better it holds up when put to glass. I have no idea how many 6 tooth blades I have messed up by simply touching glass, not talking about cutting through, just touching.
The best I've had so far was a three tooth skip.
Still, I normally grind off any excess limb material. I have a 4"x24" ossiclating sander and finally changed the belt on it yesterday after building 7 bows.
