In my book, unless I am on fire or so short of fuel or somewhere to land, it is a g/a. You would be landing un-briefed, with no real idea of stopping distance, required brake and ?reverse? settings etc, and the safest option is to g/a, try to sort out the problem, re-brief both a full-flap and reduced flap landing and come in again. Then you have it all covered. I vote for the skipper's decision.
