I have a 32-2 but have also been on the pointy end of discussions of performance sails for a 50 foot race boat. Most of the laminar sails are the same. The sail cloth is made overseas, mostly in Sri Lanka, if I recall. Most have panels premade and they sew them together elsewhere. Many of the big companies like Quantum, Ullman and UK buy their cloth from the same place. North's 3DL and 3Di may be made in country and their claim to fame is that they do "continuous yarn" weaving. I know they have a big place in Nevada somewhere, in which they lay the fibers down on mold to get the best shape. I've heard that is mostly a marketing gimmick.
On VOR, I have a kevlar main from Ullman and a 3DL #2 (about 140) from North. On the 50 footer, they have a Quantum main, a Quantum #3 and two North #1s. From these two boats, I have found that I like my North #2 but the seams started to go prematurely on the Light/Medium North #1, which is their primary headsail. The Quantums are good sails. I have been personal friends with the guy who runs the Long Beach Quantum loft here for more than 15 years.
I specifically selected a #2 (140) to go on my new furler. I made that choice because it was my understanding that the draft of a #1 has to be altered slightly so that it can roll properly on a furler and the draft doesn't have to be messed with as much on a #2. The draft can be truer on a non-furling sail. Anyway, that's my story and I'm sticking to it. I purchased a Code Zero to bridge the gap between #1 and #2, where the only performance lag I have in my headsail quiver is that light air closehaul, which a 32-2 sucks at regardless of the headsail size.
Hope that helps.
