yeah, size is pretty much my only concern with the 702 at this point. ease of use is a big one for me though, and the 7 serries seems to have that in spades. I might be looking at the pda setup if there were a more viable stealth A>D around.
I guess I am kinda overconfident about the stealthability of the 7 serries. I can remember sneaking the 170s, a stand, the V2, and a DAP1 past a pretty thorough bag search, and after that, The 702/722 seems kinda paltry in comparison. *Not that I'd put up with something that was even remotely that much hassle ever again*
I guess I'm trying to figure out what situations I'll be in (and how often) in which I could get the sax>r-09 in, but not the 702. at the moment I'm thinking it's not that often.
