Personally I don't like the bungee return type systems since they seem to feel like you're constantly having to balance against a bungee cord and/or the line's position is restricted.
I use the stock fat braid rope righting line tied to the dolphin striker and thrown over the hull. Take the line and wrap it around your harness hook one or two times and hand hold it. You can stand like this all day and your arms won't get tired.
This past weekend I flipped during a regatta (Noreaster' in the mid atlantic that had winds gusting to 30mph while we were trying to race on sunday) and even at 205 lbs I was unable to get the boat up (bows refused to turn into the wind). So I'm considering getting a righting bag to add weight if necessary.
I weigh 200 lbs and don't need the added leverage gained by pulling the line over the hull
Throwing the line over the hull doesn't gain you any leverage for righting the boat, all it does is change the loads on your body. Only thing the boat cares about is your angle to the water. It would be the same as if you moved your trapeze wires up to the tip of the mast- if your body's angle to the water stayed unchanged, there would be no effect on righting moment.
