So I am planning on upgrading from Campagnolo Record 8s to 11s this winter. I want to be cheap, to keep my bike looking as clean (i.e. vintatge, its a lovely red Bottecchia Professional), and to get easier climbing gears (39x25 is easy as it gets now, NOT fun climbing from the valley to the Blue Ridge Parkway), i'd also like to use a shimano 11s cassette/hub so the wheels (after a cassette switch) are compatible with my CX bike. Here is what I am thinking. I'd love to know a) if it works b) pros/cons of compact crank vs. big cassette

Group
Shifters: Campy Athena 11s
FD: Campy Athena
RD: Campy Athena 11s med cag
Chainrings (on the old 8s crank):Stronglight Dural 53/39
Cassette: Ultegra 11s 11-32
Chain: Ultegra 6800
$451 delivered (Ribble Bikes shipping to the US)

This lets me keep my old Record Ti brakes and crank arms and BB. I am planning on building wheels from Bike Hub Store hubs laced to either Kinlin or H+Sons rims.

Thoughts? Will the campy RD work with 32 cog cassette?
