I had a 55 first run Appaloosa. The only major shortcoming of the 55 Appaloosa for me was the TCO, and my opinion that it should have been a 650B bike. My every day commute involved two spots where I would have to execute a tight weave through the access gate to a bike path, and at both spots I'd kick the fender hard.
I think the even-more-current Atlantis and Appaloosa may avoid TCO as well, with an even longer front-center. Those bikes will require some sort of swept back bar for most riders. My Atlantis is that brief combo that has a short enough top tube to run drop bars, and 650B wheels to avoid TCO. For those reasons, it's my perfect Atlantis. I wouldn't change a thing.
