Well, actually after that I indeed did get a tripod. (Some of us are
mere desk workers and do not have the advantage of buffing ourselves up
via splitting wood, so I had to find some other way to keep the antenna
aimed accurately.)
What I ended up doing was, I homebrewed a mount out of some PVC pipe
joints and a 1/4" bolt that fits the tripod shoe. The PVC pipe was just
large enough to fit over the boom and still allow for lateral movement,
so I can still adjust polarization while it's mounted.

With the Arrow so mounted, I can still adjust roll (up to 90°, which is
enough), pitch, and yaw without feeling like my right arm is on fire
when the pass is over. At the moment I'm still using my camera tripod
with ball mount (which probably cost more than all my sat gear combined,
ugh) but this weekend I'm going to get a dedicated az/el tripod which is
lighter and easier to set up in the field.
Using this setup, I hope to one day achieve my Holy Grail of sat
operation: using the Alaskan Arrow to complete a QSO via FO-29 with
actual Alaska.
