6700/6703. The triple is what makes it for me. The other two don't offer triples.

• My pure roadies are standard doubles, and I'm a solid 39-ring rider.
• A compact would have me shifting the front in the middle of every block.
• But, I need the granny for hauling groceries up the hill and slogging through the snow with the studded tires on.

For these reasons, all my commuting/errand bikes will always be triples.
