Has anybody read the article on Silvio Dalla Torre in the recent Double Bassist and if so, do you have any thoughts? Check out http://www.silviodallatorre.com for lots of interesting information. I found the idea of the (really) heavy bow interesting. I play with a 148 gm bow now and have often wondered if especially on the unwound gut that I play on, whether an even heavier bow would be better. I have never used a lighter bow that worked well for me. I find a heavier bow (all things considered including balance, etc.) starts and tracks on the string better, gives me a better tone, and is less tiring to play.
