You're really looking for the greatest power margin available, basically where you have the biggest amount of power to reduce your RoD and stop you hitting the ground.
Lots of power - will possibly allow you to HOGE and the make a vertical descent.
Little power - means you have to make your approach shallower and possibly have to execute a run-on-landing as you do not have sufficient power to stop a higher RoD and possibly not even enough power to maintain HIGE.
Once you have done your power check, always apply that the power you have worked out to have available, the reason for this is to check that you ain't going to overpitch/droop the RRPM... best check it up high then discovering when you are trying to recover from the descent at the bottom of your approach!!!
