One observation I don't think has been noted in the thread -
For an OEI feathered landing on an aeroplane with big wind wallopers there is a significant yaw due drag on the operating engine(s) which won't be seen with a zero thrust situation as all engines go symmetrically to idle at the flare. I've only seen this on the L188 (4 x 4000 HP as I recall) and it certainly gets the pilot's attention if he/she is half asleep.
I don't really think that this problem necessarily warrants real OEI landing practice and, in general, such aircraft usually will have access to simulator training. However, folk should be aware of the problem so that they don't get caught out when the throttles are closed.
Can't say that I've ever noticed any yaw on lighties, though.
