I will always try and do some kind of flare, but do not ever try and zero out the air/groundspeed. I have seen guys do it with runway lights off and only using the landing lights, then see them doing it with runway lights on and landing lights off. I'm afraid that my cojones aren't that big.
Then I was introduced to these wonderful little pieces of equipment called NVG's.........full downs are now much easier!!!! Spoiled I guess.
