Swing-out rotor
A swing-out rotor lets tubes rotate to horizontal under load, so the layers stratify flat and perpendicular to the tube. The draw is easier and more repeatable across staff. The tradeoffs are footprint and top speed.

Flat layers
Figure. Under load the tubes swing to horizontal, so the layers stratify perpendicular to the tube. The draw is easier and, more usefully, more repeatable across staff. The tradeoff is footprint and top speed.
In practice
Solid PRF protocols specify a horizontal rotor. If PRF is anywhere in the protocol library, the rotor question is settled before it is asked.
