"Also attractive for touring with a wide gearing range and what I see as much easier starts on steep pitches. My wife has no issue getting in sync, but getting OOP is more difficult, at least for my wife. Standing is a bit trickier and I don't think it's the strong point of an ICS configuration."

I was waiting on Ricks comments, J & I agree, the gearing is outstanding for touring. Judy has a bit more trouble with sync and we are working on better ways to stand. It goes without saying that it IS nice to be able to stop pedaling without messing with your partner, but you really don't need to do it that often, people have been riding linked up for years.
