Originally I listed this route as a comment under Call the Copps, but having climbed it twice now, and both times finding it in much better conditions than CTC, I think it warrants a description.
The climb is an excellent, moderate, trad, mixed pitch with fat reliable ice by Flatiron standards. The route starts up dryish rock before entering the RFC. Eventually, enter a chimney with okay ice for feet. After a small cave, exit up the A-frame roof, then step left across a slab to some trees.
The route can be linked into CTC's ice slab by ascending another shorter RFC, then downclimbing easy terrain to the slab. Alternatively, rappel 100' from the sturdy tree back to the base. You can descend straight down the gully to the base of Freeway. At some point you will reach a short rock step where you can either downclimb or rappel.
This is located just right of the regular first pitch of Call the Copps on the 2nd Flatiron. Follow the approach beta for that route up to the gutter. Ascend easy rock, then downclimb to the start of Call the Copps. Hike around the small buttress toe of p1 CTC, then continue up and climber's right to the 2nd right-facing corner.
Single set of cams and nuts to 3". Protection is generally adequate.
