here in Canada the list price for the 920 is a whopping $2400, thats a lot I find for what it is. I'm not keen on doubles but I suspect that from what you describe what you want from a bike (and loading not too heavy) this would work well.
I know some of us discussed this bike a while back and wondered how the 28 spoke wheels will be.

from reading descriptions of folks biking in Iceland, the neverending factor is the wind, a real slogfest apparently. I guess you really just have to have that in your mindset before going and factor in short distance days because of that at times.
