If you get a standard short cage instead of the GS (long cage) and the shifting to 28 isn't perfect, you can add a Roadlink.
It looks in the pics like the upper jockey wheel on the 7800 is a sealed bearing? I've only seen jockey wheels with the removable bushing. Is that cleanable? Or is it more of a replace-as-a-unit type of thing? (Though I'm sure a sealed bearing jockey wheel will last pretty much forever.)
Great tip on the Roadlink, I didn't even know those existed; just reading about them now.
