Goddamn, I am rubbing my hands together just for you. I am in the market for a new bike too, also eyeing the top range Bianchi. I admit, I am a European bike snob but have had a few change of heart because I know the Specialized are such a damn good bike.
Raced for over 14 years in my youth, but have been riding very fast training rides for over 30, since I was in my teens. Lots of saddle sores and miles with that saddle up my ass. I just started riding again a little over then 10 years ago so I know all about wanting a new bike. I have a Time now with Dura Ace I am in love with that bike. The snap is all there when I get off the saddle unlike some of the older carbon frames. I love carbon, and I grew up riding steel and alum. (I actual like). Get the Bianchi or the Spec. Roubaix. they are both great products.
I like the semi-deep dish carbon wheels. Just bought a new set of Enve. They feel great off the saddle, which is a must for me and the aero benefit is great too. Get a wheel that's no more then 40 mm in the rear and not more then 30mm or so up front to prevent getting blown all over the road by the wind. Enve sells them that way just for that reason. I have only a little over 100 miles on them, just two rides. They climb very well. The other reason I like the deeper dish wheels is that they are much, much stronger, then traditional wheels. I am hard on equip, and my old Zipp 404 or MAvic Cosmic do not need truing after three seasons. The modern carbon wheels are that good. Zipp 202 Firecrest are the wheels for you if you ask me, but they are a bit on the $$$ side. About 2500 + for a set. The old bike bike racer in me do not really like those sports endurance bikes. They do not have that sharp, snappy feel coming out of the corners. I call them lazy bike. I personally stick with traditional road racing bike geometry. Many newer bikes have 28mm tires to smooth out the chip seal roads. I still use 25 mm tires and pump them up to 105 lbs. not 120 like the tire mfg suggested. Love that supple ride.
I have a Ridley too, but that bike is very stiff laterally especially off the saddle, but for general riding, its not too bad. Another bike to look in to is Canyon. This one is greatest bang for the buck

Works flawlessly. Olny difference is that DA is a tiny bit lighter. I wouldn't get campy anymore. I grew up riding Super Record but switched to Shimano and never looked back. I love Campy, but why pay more? They work the same if not better IMO. SRAM isn't a bad company neither. I had them on my bike, and have never missed a shift, ever but I like Shimano's feel especially DI2. Best way to describe is PDK. I wouldn't buy a bike without it. Get a compact crank if you need the gears for climbing. I dislike them, and still ride a 39/53. Next bike will be a mid-compact, 36/52 instead. Getting old.
You will have a tremendous amount of fun on a road bike. I going to be 54 at the end of the year. I try like hell to keep riding a couple to three days a week at least 160 miles to keep up with the big dogs at our saturday ride. CV 19 put a stop to that, so I will have to wait. These animals finish 45 miles in under two hours, 10 miles of that is up hill at the end. Avg is about 22 mph
