Great updates, Chris! You'll need to take a few independent "garage door" shots of each so we can get a nice clear view of your handiwork.
I like the Specialized saddles. Are those leather?
Also didn't know your twins were different sizes. Assuming they're set up the same fit measurements, any preference between the two? I always thought the 22" (54.5cm) Schwinns were too tall for me, but with perfect TT (I have a longer torso than legs), so thought about sizing down and rocking an extra long stem, which isn't ideal.
