220 is very important to me, especially when I head to Europe with 50 to 60 rolls of 220, compared to 100 to 120 rolls of 120 film. I still have a freezer full of Ilford FP4, but when that runs out, I hope Kodak is still spooling Plus-X in 220.
Ilford 220 is prone to winding loose, compared to Kodak. A few years ago I noticed that the slitting of the paper leaders formed a subtile edge ripple, which may have prevented a good tight wind, especially at start-up. Anyway, that's history now...
When I change film out in bright sunlight, I carry a small patch of dark cloth which I drape over the camera to subdue the light. On super important occasions, I'll carry some aluminum foil to wrap the rolls.
In the darkroom, I develop a 4 reel stack of 220 in large acrylic cylinders. In an evening I can do 4 or 5 batches, which is the equivalent of 16 or 20 rolls a night. Let's see you do that with 120.
