I'm a fan and daily user & abuser of one of the early fiddlerman Carbon Fiber bows and it's still rockin'.

I love it especially for my electric violin. I have wood bows, some quite old and the have their own sound as wood always does. Kinda depends on the instrument.

One of my really old acoustic violins just won't play well with the CF bows but the other one does! Go figure. And the electric plays well with both but I prefer the CF because it's fast in the hand and easy to move and is lighter than the wood bows by a few grams. At first, a few grams doesn't sound like much but it is when considering the amount of down pressure you apply to make the strings vibrate.

The type of rosin you use, the temperature of it (Thus the stickiness of it), the width of the hair, the age of the strings, all these things play an important part in getting a good clean sound...and don't forget your ability to manipulate that bow to make all those wonderful sounds.
