    In the JOBO, after the first roll is loaded all the way to the center spool, the little red tab is pushed in to act as a stop, and prevent the overriding of the second roll.
    That's fascinating. They're el-cheapo Samigon reels, sold in an el-cheapo Samigon kit. :-)

    I love how this "simple" question has grown -- like some sort of culture in agar.

    Why? Again it really depends upon the dimensions of both the reels and the tanks.. There are some large diameter plastic reels around (Jobo 2501 and 2502 for example). and there are some small form plastic reels (Jobo 1500 series) and then some a little bit larger in diameter (Paterson, A-P knock-offs) and then there are stainless steels reels in all these rough dimensions (Hewes even makes a few in Jobo 1500 series dimensions with normal and large hole to fit the standard Jobo column). There are then some stainless reels that are large in diameter. I have an Ilford Autowinder 35mm tank (designed for 72 exposure like the Jobo 2501) whose diameter is quite a bit larger than other inversion tanks (and en-par with the pre-WW-II Jobo "rotation" tanks). A 1500 reels would just rattle around in that steel tank...

    Now to the question what is better.. Stainless steel or plastic... first there are quite a few different plastic systems.. The Durst system, for instance, is a center loading reel not much unlike the Kindermann.. then there is the Jobo 2501 which is too "center loading" and uses a special loader (in fact the reels does not contain spirals but gets them when mated with other bits for the process of loading). Then there are the walk-in reels.. how well these work depends upon the plastic they are made of and their condition (old plastic reels that are filthy can be hard to load) as they depend upon the film gliding against plastic... then there are loads of warped stainless steel reels (some seem to be made warped in Asian basements), some with clips and some with hooks... then there are the tanks... some like Honeywell/Nikor with leeky tops (even when correctly matched)....

    Then there are the systems around the tanks and reels...

    I personally think stainless steel reels and cages (lets not forget sheet film) is best in dip and dunk systems--- and all the manual systems I know use plastic for their "boxes"--- and plastic doing the rest..
