i am interested in trying a 1:2 spin halyard set up. Imagine only having to pull half as much line. That would speed things up.
Works really well for the first 9/10th of the uphaul and then the spinny starts to fill, the last 1/10th is just a pain and 3 out of 10 hoists you can't complete without going dead down wind, don't ask me how I know.
