I chose finger style, mainly because you can get different tones just by moving your fingers around, digging in, plucking different ways. It just seems to bring out the best on a bass guitar. I started out playing guitar, and when I made the switch to bass, I started out using a pick, but found it very awkward and clumsy for me, and I was always dropping the pick ! Finger style came very natural to me, so I've stuck with it. As far as slapping goes, I use it to accent notes, or to drop in a little funk style slap in a song, not as an ongoing style in my playing. I admire the guys who can play that style all night, but, frankly, and imho, they all begin to sound alike after awhile. Since my main gig is a variety of genres as far as music goes, finger style just seems to do it all.
