Steve 76,
The constant attitude EOL is a splendid technique when you have to get the speed back to make the intended (or only available) landing site. Aim for between 30 and 40 kts, maintaining positive groundspeed and ignoring airpspeed fluctuations in the latter stages due to windshear or turbulence.
This really is a question of waiting for the green to turn to grass as you want to apply the first bit of lever (a check just like the variable flare EOL) at about 30'. This will tend to pitch the nose up so forward cyclic is required to maintain the attitude but the RoD will start to reduce. The end game is to get to about 5' with enough Nr to cushion the touchdown ensuring you are striaght without skid or drift and the skids are level. Some prefer a gradual pull from about 30' as opposed to a separate check and cushion but it works pretty much the same (IMHO it is more difficult to judge the rate of application of lever this way but others like it).
