I dont agree with the last post entirely.Some time ago when my job was to route and airport check Captains into VNKT, one of the required checks was a VOR approach to 02 but followed with a circling approach to 20.This was practiced first in the SIM.The actual circle, WX permitting followed.No one failed to my knowledge, but I would not call it an easy exercise.Very good planning and handling was required.This was in a very large jet.
