Thank you for all your answers, I was extremely busy during the week and haven't been able to answer so far.

I will check out the synapse as well, although I'm already on the side of the supersix, since I was going to get the CAAD anyway and it's the same geometry but with carbon. Whichever bike I get, I will probably get it with a triple crankset despite the less smooth shifting that's supposed to bring with it, since there are many hills over my area that top over 10% incline,
