Oh, I remember that thread now! Good times.
I did exactly the same as you at first, used fingers for practice and rehearsal, stuck with picks onstage. Until that one night. I can actually still remember the moment, watching the pick drop in slow motion towards the floor while I tried to decide whether to grab another pick off the mic stand, or just go with it. I went with it. You'll prolly have a similar moment when the time is right. No need to push that, not while playing for a crowd, at any rate.
