Ha! That's a great tip. And I also love my Paterson tank and reels for 120. I even develop my 4x5 using taco method before I get the MOD thingy. And I also have a spare set of reals so I always have dry ones to rotate between. One thing I noticed is water likes to sit around the ball bearing and that's what may cause problems. Make sure you dry that part with a paper towel and you're good to go. Never had any major problem with them. As opposed to my failed attempts at steel. I am getting a few Hewes reels (supposed to be better) only because I inherited a bunch of steel tanks so I might as well use them. But I'm not optimistic...
