Bob, the difference in set up time between a Uni and a F 17 is significant. Lots of do dads to mess with on the F 17, thats what I was whinin' about. The bridle, the pole, the boom, the sheets, the halyard, the hair spray can for the shute ....But....they do fly downwind..don't they. Geez, I sound like I'm talkin myself out of it...don't mean to.
