Dump the Pole. Most other posters seem to have become embroiled in a favourite Rotorheads topic of Vortex Ring.
Just to re-iterate what a couple have said: a downwind quickstop does not end with you hovering downwind. Imagine it as the helicopter equivalent of a handbrake turn in a car. You end up pointing in the direction that you have come from, ie into wind.
There are two types: flare and turn, and turn and flare. Heights and speeds will vary according to type. For a flare and turn, I would be flying downwind at 90kts and 50'. Initiate with flare, maintaing height and direction, and then start the turn into wind to end up pointing into wind with about 30-40kts still at 50'. Come to the hover, then forward and down.
For the turn and flare, same height and speed, but initiate with a turn and then flare off the speed during the turn still looking to be 30-40kts and 50'.
The difference between the two is the flare and turn gives you a (comparatively) long narrow flight path, whereas the turn and falre gives a short wide flightpath.
I'm sure others will have different techniques.
