I also have a CAAD 12 that weighs 17.5 lbs w/ Speedplay Zeros and Mavic USTs. I'm a recreational rider so a CF frame doesn't really interest me. Just not worth the money it would take to be "better" than my CAAD 12 or my Guru Sidero, actually. If I was choosing between spending a bunch of money for a CF frame or spending that money for a high end gruppo....well, the answer is easy for me.
