I think that this article demonstrates the necessary flexibility of all types of lite, from ultra to uber. As some posters (Vick Hines, Michael Wands) have pointed out, in south Texas (my neck of the woods) sub-5 is NOT SUL. You can walk out your door with a poncho and a water bottle and be just fine - if you even think you'll need the poncho - through three seasons. By the same token, if you dare wade back through this thread, you'll find a similar discussion - is SUL actually sub-6 if it's winter? Taken to the extreme, and a baseweight that is double the typical UL load might still make the UL "cut" in conditions as extreme as Denali's.
Maybe our criteria is percentage of a standard load? I don't know how you determine the "standard" load, but that's one way to approach it, or at least think about it.
And yes, Matt and Agnes' gearlist will be up soon!
