LLRR definitely wouldn't work. But LRLR will
still tend to stray from
the vertical because the sloping tops all slope the same way. That is
why I suggested LRRL. This zigzag reverses the sideways displacement
that occurs in each pair of layers, thus rising vertically and being
therefore more stable than LRLR.
To flog a dead camel, and carry forward a pointless thread, I still don't
see how LRRL is any superior to LRLR. LRRL would be noticeably crooked,
and might not even stand.
