Time for me to interject as the OP.
My bass journey began on classical guitar and that is the technique I brought to my bass playing.
I've always played fretted. Over the years I've had a fiddle with fretless, but never got on with them.
That is until I played Frank Black's Rob Allen Mouse at the last SE Bass Bash.
I have being fortunate to procure my own, which is lined, and after initially having my gaze locked on the neck, I'm now playing with a mixture of neck glancing, positional play, and by ear.
