Why listen to hearsay from someone who has never tried it? Keep your bows into the wind in irons. Clip a trap wire into your harness then lean over and use both hands to re-attach.
That might work on a relatively flat lake in 15mph wind, but I'd love to see it on an open body of water in a real breeze. Things have a tendency to move around quite a bit in those conditions.
The power pole is not a solo righting system. It is a perfect example of engineering overkill. It is expensive, confusing to install, hard to deploy/stow and gives you no more advantage than a simple righting line attached to the dolphin striker.
The power pole has the potential to provide significanty more righting moment than a simple righting line. The reason being that it allows you to get your body (center of mass) farther away from the lower hull (fulcrum) than a simple line. So your body position is not limited by your height, only by the length of the pole. It also looks pretty simple to deploy to me, just unclip it from the back crossbar and swing it out.
