I just made my first trial of a prototype Genoa. I was really happy with the results, but the roller reefing system is much less hassle free with the halyard attached (and yes using the pre-installed web on my 2012 TI). I'll have to post more pix after I make the real sail (I have the cloth and materials ready to go).

The design doesn't use a forstay, but tensions the jib with a halyard, and what I call the lower tensioner. Both run forward to a double block at the nose, then back to traditional cleats on the aft akas. The sheets run through blocks at the forward handles, and then clam cleats on wooden block installed on the second set of handles (have to watch out for tiller clearance on the port side).
