It is interesting about my experience with dural drillings. I've only owned a few. I have had more steel BBF'S and drillings than Durals, but I never had an off face or problem dural, but had a number of steel ones that were off face. I never thought about it until just now. I always sort of thought dural wasn't as tough as steel, which only shows my ignorance. They sure are a lot nicer to carry and come up quicker. Probably just coincidence, but interesting.

Just a hunch, BF. The Dural may be more elastic than steel, allowing it to return to shape.
