Tim,
What kind of main do you have? I have an Ullman now- probably similar to Robi's and I have a Glaser on order so I will be able to do the same comparison- same with the spinnaker. I have a pic of Robi's main that he had during the seminar and that is clearly a different cut than recent sails.
Nice you guys could go out and sail one on one. I wish I could do that. I am trying to get together with the Blade on pensacola.
As for other sailmakers in on the F16s- when I asked the question a while ago, Landenburger (sp?) and Ashby were the others that came up.

The thing I have noticed about the Ullman main I have is that it is somewhat full.. but I don't have that much experience with uni sails (or any sails for that matter <img src="http://www.catsailor.com/forums/images/graemlins/frown.gif" alt="" /> ). Compared the the HT uni sail it is MUCH fuller.
