I'm torn about the whole compact crank thing. But also a lesser man than BBM, and as such unable to stick a triple on my roadies.
Currently trying out a compact (again) on my Merckx w 8 speed Campy. And it is just because of this 2 mile very steep hill on my favorite ride that really rips the cartilage out of the knees.
But in a touring realm a triple is a must. Why not? Everything is already so damn heavy.
