Love number 2!! Have the same in brown (the small version); I just love the hardware on it!
But also love number 1 in snakeskin?
The bouvier is also verry nice, but is a bit more classic, I think.
this is hard!
I'd keep #1. It's got a unique look that will "age" well. I think #2 will get "boring" after awhile and the white will get dingy as time goes by. #3 is nice, but I've found that the Bouvier gets kinda "old."
