I've only been home developing for less than a year and up until now I used only stainless steel tanks and reels. I don't have a dark room so everything is done in a dark bag. I've found that 120 film is quite easy to load once I got the hang of it. But try as I may, I frequently struggle with loading 35mm film onto the stainless steel reels. So I finally purchased a plastic AP tank to use with 35mm film. It is similar to the Patterson but was way cheaper. I did my first load the other day and was pleased at how easy it was. So my question has to do with agitation. The tank comes with a tube shaped agitator that is inserted down the center of the tank after the film is loaded and twisting it spins the whole reel, agitating the film. I'm wondering whether it is OK to do all the agitation this way, twisting the agitator back and forth, or whether it is still necessary to put the top cap on the tank and do complete inversions for agitation. Furthermore, if I go exclusively with this spinning agitation would I need to make any adjustments to the agitation pattern that I use with my stainless steel tanks and inversion agitation? Any advice will be appreciated.
