I just received a carbon fiber bow from Alain Le Gouic (
http://members.aol.com/bassbows/) for a 10 day trial period. This "classic" model is a really fine bow, responsive, has a clear sound. The nicest thing I've tried so far in the 500$ range, cheaper better sounding and better finished than the Carbow models also available here, in France ( I have not tried any Glasser yet). Its the first time I found something better than my (generic) Augagneur in the afore mentioned price range.
