100% fingers, I played jazz in school so naturally I started with fingers and all of my favourite metal bassists played with fingers so that's what I stuck with.
My setup is pretty simple,
bass > MXR DI+ > Scarlett 2i2 > Reaper
I'd love the option of being able to mic a cab but the noise makes it unpractical for me.
Maybe the fact that I'm using low gauges doesn't help the tuning although other people I've talked have found the same. Changing the string tension over and over is going to wear the string out sooner or later, it's just a question of if you keep the strings that long.
Gig bag most of the time because it's easy, goes on my back and leaves my hands free, only exception is if it's got to go in a van with loads of other gear, then it's a hard case.
