I used to use Kindermann SS reels but I have recently switched to a JOBO CPP-2 since I use the expert drums for sheet film development (and am extremely pleased with it). I would also like to use the processor for 120 film, but I have been having trouble loading the 1500 series plastic reels and have ruined some negatives. A friend of mine suggested using AP reels instead, they supposedly fit in the JOBO 1500 series tanks but the center hole is somewhat larger, so the reel does not fit as tightly which doesn't seem like it would be a problem for rotation development. Maybe I just need to practice more with the JOBO reels? I know they have to be absolutely dry, I think I have been putting too much pressure on the film sides when rotating or maybe getting the initial loading wrong (at least this happened to me a couple of times when practicing in the light, one side of the film was in the correct slot but I had inserted the other side one ridge too far in. Does anyone have experience with using other reels in the JOBO 1500 tanks (I have heard there are also SS ones) or tricks to load the JOBO reels reliably?
