hi bassists. i recently busted the neck on my bass, and while it was in for repair i thought i'd get my white bowhair replaced with black. just for kicks. i have another bow with white hair so i figured i'd try black on this one. anyway - i've always heard that black hair is 'grippier' than white hair, but have found that not to be so in my case. in fact, it has significantly less grip (virtually none, actually) than it had before. i even tried applying a heavy dose of rosin, but no dice. i mean, the rosin helped a little. i compared the bow with black hair to my other bow with white hair and there was no comparison - the white hair worked, while the black hair just slides and skithers all over the strings. is there some 'breaking in' period for black hair that i don't know about? i'd hate to think i just wasted $50 for a rehair, only to have to spend another $50 to put white back on. has anyone else encountered this?
