i mean tremelo picking.

You shouldnt really be tremelo picking lead lines unless you're stressing a note, otherwise it can sound sloppy.

I would only allow a VERY small amount of the pick to extend from you fingers, and only use the index and thumb. Personally, I trem better with just two fingers, but then again Bruce Kulick and Eddie Van Halen use their thumb and middle fingers, so... It's kind of a comfort/speed matter.
