The real issue here is whether you have worked out an alternative to the 11speed chain tool from Campy. If you haven't yet solved that issue (do a search), then you are not out of the woods with regard to a pretty steep price difference (should you need to buy the tool for the 11 speed chain).

Otherwise everything above is spot on and I would recommend any 2009+ stuff as the ergo levers are a terrific improvement. Since you find value in swapping wheelsets with 10spd, I would stick with that...simplicity is elegant.
