Not sure I have good photos, but Brett's compression ribs are pretty conventional - 0.025" square at bottom approximate with arc ribs glued on top. For the vertical part he uses three bits of 003 boron, pretty equidistant IIRC.
That being said, banana ribs (i.e. 5% arc on top, 4% arc on bottom) are pretty common. Both work fine. Make up a few of both and use whichever is lighter.
