I think the sloops have a clear advantage in winds over 10 knots. Still, I'd rather sail at a disadvantage than not sail at all. It isn't as if I'm missing out on any trophies.
I think there is a challenge. For someone who thinks they are a world class sailor, climbing to the top of the F16 world, uni, would be like climbing Everest.
I agree it is much harder to do well uni. I think it takes more practice, a slightly different setup, and it certainly takes more strength / endurance. I'd like to see some talent try it. Greg is obviously accomplished, but was handicapped by not having a cleat. Plus, it's not something you can justnjump into and expect to do well.
I think the potential is there, it just takes more to get there.
