I've been using Buzz bag for a couple months and it's just great. (One annoying thing though : Velcro on cellphone pocket isn't strong enough) However, I sometime have to carry my camera + PB12" with me.
I only have the Buzz bag for my PB, and another Tenba for my cameras. But none for both of them. I'm not hoping to carry all my SLR bodies/lenses with PB. Maybe just 1 SLR body + Flash + 1 short lens + PB.
Any recommendation ?
