I've been happy with Kindermann tanks and reels for decades. Just bought a couple of "new" tanks too, that surprised me by being larger in diameter than I'd seen before. And with larger-diameter reels too, evidently for 220 film, to give them more space between wraps of the film and more liquid volume to handle the film surface area. Now I have two of the larger tanks, one for one reel and one for two reels, and looking forward to running some 220 Tri-X in Diafine!
I did already have a 220 reel for the smaller diameter tanks, which used smaller gage wire and packed the 220 into the same diameter as a 36-exp roll of 35. I used it in a 32-oz tank with a couple of empty reels so it would have adequate developer. I expect the new big tanks to be better for 220.
I like the reels that have either a spring clip or toothed clip at the core, but it's important to have the film centered on the clip! Otherwise, there's grief in spooling on the film... I agree with others that it takes a bit of practice to get a feel for it. And also agree with the so-called "wheelbarrow" method, assuming by the description it's the same thing I do, in pushing the film lengthwise to keep it looser in the spiral rather than snugged tight. This helps prevent getting off-track but also means less length of film that won't fit into the spiral! Otherwise there's usually a few inches of a roll of 36 that's free to flap loose outside the reel and possibly be damaged.
