Fun route, we used Rad Cliff to extend our day after climbing Triassic Sands. I led this decent tall corner/chimney pitch. Single rack to 4" was adequate. Maybe double up on a 2" and 3" for your station. Traverse to the far tree to the right for the rappel. You have to downclimb just a tad at the end with a 60m. Fun, complete turnaround chimney move about half way up is the crux.
