After getting my First G, I've got the hunger for just one, or maybe two, more! One that I'd really like is the G7900... but no stores near me carry it, so I can't try it on. I'm sporting a wrist just a bit over 6 inches, so I know it's cutting it close with this one. I've seen posts here with others with small wrists able to pull it off, so I'm tempted to try!
In terms of dimensions, the GD350 seems to be fairly similar, and also looks like it has the hinged strap/wings combo. It's also in most stores near me ready to try on. Does it wear similarly enough to the G7900 that if I were to try on a 350 I'd get a pretty good idea of how a 7900 would fit?
