Every pilot should give serious pause prior to balancing fuel after an engine failure.
Many times you will be on the ground prior to a serious imbalance....or if you must crossfeed...do it with a serious imbalance pending...and give it great consideration.

After many years of V1 cuts around the pattern to an engine out landing, I can't think of an airplane that wouldn't at least be approaching imbalance limits on such a manuver. Most of the time would exceed. Now I don't think the airplane is going to fall out of the sky if it exceeds imbalance limits, but I think it would be a hard sell to the FAA to say "our new procedure is no fuel balancing, regardless of limitations being exceeded, just in case there might be a fuel issue."
Air Transat was a unique situation. They were late catching the excessive fuel consumption, then the captain refused to believe it for awhile. Don't know what relevance it has to an engine out situation.

If you are going to exceed imbalance limits...then crossfeed. It seems I fly the sim with almost 100% of pilots that instinctively reach up and open the crossfeed valve after securing the engine...then forget about the fuel until after landing...as if this will keep them in balance. This is not crossfeeding and will many times take you further out of balance. That's why I state that crossfeeding should be done with great consideration...and not abitrary action.
I like what Doug said previously...isolate the fuel systems until necessary to correct an imbalace. Immediately opening the crossfeed valve is arbitrary and unnecesarry.
