I think that acoustic guitar is such a subtle but expressive instrument. I like to try a lot of different stuff when I play it. I'm the lead player with my band...so generally these days when I play acoustic it's done finger-style and not with a pic. But when I play it just depends on the song and the dynamics of the song on where I play. I generally don't hover around the bridge though to answer your question sort of round-about-ly.

I usually only go there when I want certain notes to stand out...usually at the end or beginning of a song or sometimes during a break or pause. When I'm standing on a 7th or 5th I'll generally strum close to the neck for a looser and less defined sound. But again...it all depends on the tune.
