I've have/had rotor, Rinpoch, dds and 75s. Go with dds (my 2p). Rotors, (unless they are the pre 2015 garish model) cant really handle everyday skids. I'd still be running dds on my parallax if I didn't have Rinpoch. Rinpoch is pretty good, the bb is decent and the chainrings are pretty well made. DD's As ellis said, switch out the bb for the ultegra and you're good. I still use the original "crank bolt" just covered with some black tape. It no longer comes loose, it has been around 8 months.
