Charles, Were you building X4? Cross 4 works fine till you try to get the spokes tight enough to be stretched. Then if you flex the rim a bit sideways it will relax into a taco shape. Happened to me pre-tensioning a wheel. And of course the 1320 wasn't very rigid(a).

27" or 700? If your rim is wrecked, I have a pair of NOS 27" 1320s but they are blue label.
