I am just starting to use picks. I have yet to actually get a bass pick though I've been using my brother's guitar picks and they are a wee bit too small (I keep rubbing my pointer finger against the strings and it kinda hurts after a while). I was wondering what size you would say for rock style music. I was thinking a 1.5 rounded triangle but my brother says a 3mm rounded triangle would be better... what do you all think? I'm sure this has been asked before and for that I'm sorry about bringing it up again.
