Congrats on your upcoming retirement
There are bikes with which you connect instantaneously and that you will always like and others that you will feel neutral or disappointed. This is why when I decided to have my roadbikes assembled to make sure that the frame I have bought would be something I love and is unique to me and my tastes. You have one of the best collections of road bikes, so I am sure you will enjoy what is staying in your stable. Same for my mountain bikes, I have reriden with my Kona that I haven't riden in years and I immediately start to appreciate again the lively and nervy ride that it is. Rediscovering bikes taht you haven't riden for some time , just makes you appreciate them more for their qualities.
