Nice build! The comfort of that bike impresses me every time I point the bike down the dirt roads and fire at will. Glad you found the same.
How do you like the $300 sprint shifters? Dialing in the new shifting system to work as you want is a great way to personalize the performance of the Di2 system, too. The speed at which the multi-tap engages and the number of cogs that move when you hold down the button are all adjustable.
The 3T wheels were just part of the rest of the 3T package, the price is considerably less than the Zipp 303/404 option and I can't find a $6000 road bike that comes with aluminum wheels so the carbon hoops seemed to be the right spec. Wheels are getting to be like saddles anymore with guys buying condition specific wheels based on their strengths and courses. I use the Shimano C75 wheels but I'd never put them on a bike at the OEM level. The 3T wheelset is a good balance for an "all-rounder" I think. Using 50mm deep wheels has proven to be a bad choice when dealers try to sell bikes to novices on test rides in Texas during the windy season.
Make sure the rear brake is centered with the spring adjustment moving both arms at the same time. The cable housing needs to be free of any kinks so assembly must be carefully looked after. The brake will invariably have a softer lever feel than the front as there is more than twice as much housing so you'll get more compression. There are also more "bends" that get pulled straight when the brake cable is under tension so you lose a little lever travel. The rear quick release might not be needed if your rim widths are similar. A simple inline adjuster might do the trick. Run conventional housing from the brake lever to the inline adjuster and compressionless (Nokon, Jagwire KEB, Avid FlakJacket, Jagwire Link, etc...) housing to the rear caliper.
