I started off on classical guitar before I fell in love with the bass guitar--where I have stayed--& only started to tinker with DB a few years ago. With her flamenco background, my guitar teacher drummed 1-2-3-4 into me for the fretting hand & 1-2-3-4-5 (in various permutations) for the plucking hand. This is etched in my mind forever. I found that there's no use fighting it; my hands are large enough. As many of you have written, no size fits everyone. Lots of variables come to play, yes.
