So, the scott plasma didn't fit- just too big. I picked up a quintana roo seduza on ebay. It showed up and I had everything switched over and built up in a few hours (would have been less if not for the PITA QR internal cable routing).
I went for a ride up and down the street and OMG, what a difference. I loved the plasma frame but this thing just fits so much better, I felt really comfortable - able to stay nice and compact. I also think this frame is more aero than the plasma ltd. There's more internal routing and the frame just seems a lot tighter.
I wish I could switch out the white saddle for a back one and eventually I'll ditch the white bar tape, possibly removed the HED decals at some point. For now I just want to ride!
