In the ~60 years that I have been developing film, I have used just about every type of film reel ever made for 35mm and 120. This includes the old Kodak reels, the Kodak spiral wound separators, Ansco reels, Nikon reels, Jobo reels .... I could go on. I've also used reels for sheet film and rack and tank. The bottom line is this. If I am careless or inexperienced with a given reel type, I have problems and need to practice. If I have practiced enough, I don't have problems. It is as simple as that.

I get a new reel and a roll of old film and sit in the light using it over and over until I get it absolutely perfect. Then I shut my eyes and repeat it. Then I turn out the lights and try again. I've worn out dummy rolls and worked for an hour with a new reel.

The bottom line to me is that all reels are good, as long as you know what you are doing. You know what you are doing by practice.
