What I don't get is "pack structure hate." mountainwalker has said it all more clearly... Of course, I don't enjoy carrying rigid pieces (particularly single-use) any more than the rest of us. Seems to me a question of balance. (Isn't everything?)
What I'll say: isn't "ultralight" truly more about "ultraefficient" or "ultraappropriate" than actual weight? I think that for significant loads (found with long trips, techy winter trips, limited-water-supply desert trips, rough off-trail travel, etc) effective and very lightweight load transfer and stability structures make the load FEEL so much "lighter" (more comfortable/less painful).
Ron, I think mountainwalker is right concerning customer base. Just make it optional. I imagine you don't like stays, though.
OK, now I'm dropping it. For this thread. In closing I'll provide a link to the other BPL (UK, newspeak) featuring a Golite Jam modification which adds 161g: Ultralight ALICE. BTW, have you seen Roger's awesome packs? TTFN!
