v3m,
I was responding to the blanket statement made by boofhead, not the conditions specific to this event.
I regularly fly into airports with 10,000' runways so ,again, I was referencing personal experience, not yours or boofhead's. I wouldn't dream of telling you how to retard your equipment. I don't know what environment you operate in. I do, however, understand mine and accept the valid reason why the mandatory use of autobrakes only applies in certain conditions at my carrier.
My carrier 'inherited' some airplanes without autobrakes installed. I could go into detail but the point is it's not always possible to teach reliance on a system if there are such fundamental differences in equipment within fleet types.
Brake cooling as I previously stated is of secondary importance (and likely not such a problem if it's below zero anyway!).
