this seems to be the ticket for a pulley in prelim testing! Hand tending is completely effortless once you pass the 45 degree mark. Adds a little bit of length to the system but the gain seems worth it. I could never get the HC pulley to work, would rotate and really mess with descent and upward tending was weird. The ring drops right into the groove with the ct pulley (this all may have been discussed, excuse redundancy if it has). Only worry is the slight bend between the ring and where it enters the pulley for descent but seems ok. 100% on par with a rope runner IMO.
