Most of the suggestions made here in good faith were not as direct comparisons. I wouldn't advise anyone to do an October ascent on the Hallett North Face, but the Flatiron climb doesn't even rank as a close comparison. I've done both the Northcutt-Carter and the Englishman's Routes on Hallett. Try something long in Eldo under less than ideal conditions (after a snowstorm) for a sample of being cold, wet, and miserable.

C-B is kinda hard for the grad. Definitely not Bo Can 5.8 by any means. Route-finding isn't the worst, but it isn't super straight forward. The Lumpys suggestions are apropos.
