I live and ride in the Bay Area and highly recommend the triple, regardless of what bike you go with.

Also, even for a test ride it would probably be a good idea to have some bike shorts on to really get a better feel for how the bike and the saddle are going to feel. (If you haven't yet been to Sports basement you should check it out. they have 3 locations in SF area: Marina, by Pac bell or whatever it is now park and somewhere in the South Bay. Anyway, they generally have some good deals on shorts and gear you will likely need to have with your new toy.)

I would recommend really getting a feel for the bike and how it handles, developing your skills well, before you toy with the idea of aero bars.
