Kona Sutra vs Marin Toscana vs ?

they are also supposed to help with stability giving the bike a lower centre of gravity. also if you head to certain places touring 26inch tires are going to be the easiest to find.
i opt for 700c its what i'm used to and they roll better on roads which is where i ride most.
i'd not checked out the soma saga, it does look like a well designed touring frame.

I'm a short arse so 26" wheels would sit me over the bike better. Also I'd probably go for large(ish) tryes for trails and rough roads.

Another CycloX/Commuter/light-tourer/winter bike option could be the On One - Il Pompino. Built up with an Alfine hub for example. (I'm getting very bored of digging winter road paste out of my rear mech.)
