The Domane I'm looking at weighs in at 17.5 including discs and electronics. Wheelset, a Bontrager Aeolus Pro 3, comes in around 1600 grams. I think their next tier is the Aeolus XXX 2 which is 1380 grams. I don't know what the upcharge is for that item but intend to ask. It reduces weight by about 1/2 pound. I would probably never swap out the wheels normally but as this is my one shot at grabbing a great bike and it sorta buries the cost, I want to at least see what the difference is. I definitely won't upgrade if it's way expensive. This bike is already lighter than my 4.3.
