Thanks everyone! Yea, it was just a momentary irrational analysis and I think I'm on the other side of it. The reality is I really want a Domane SLR disc and here I stumbled upon a phenomenal deal on an Emonda SLR and it tempted me a bit. However, today I confirmed I could not fit 28c tires on the Emonda to get me closer to the comfort of the Domane.
The good thing that came out of this is I have been going back and forth about upgrading my Domane 4.0 disc vs getting a new bike and I think that question is answered. I'm going to ride it as is (other than new wheels and Schwalbe Pro one 28c tires) and wait for the right deal on a Domane SLR.
