I currently use a deluxe Standish with 10 stacks, 8k bulk, and speed of 52. This satisfies most of my needs so I voted for recall. What I'd really like to see in a disk is a bind point. Folks would have a "recall to disk" ability to get back to where they were when somebody needed them elsewhere. Or one could park it at far away resource like travertine and not have to run back out for another load.
