Ok, that calibrates it for me. Thanks. That's the neat thing about the radical design departure. More and smaller high crowned ribs can more closely anticipate and control stiffness with a thinner panel, with less overall mass. You actually get to design the thing from the string scale out, and the rim in instead of guestimating the merits of incremental modifications to the existing design. It's still guestimating, but it sure feels a lot more sure and right to me. Again, maybe I'm just weird, but I really like it. > Many things work.

Since my worst "radical" rib crowned board sounded as good as my average 60' rib crowned/compression board of times past (far better than my worst), and I have no doubt what I'm doing now will live longer, I'm pretty sure where my money's going.
