I have been using Pyrocat Hd in tubes with Fp4+, the drawback is I can develop only 3 sheets at a time.

After returning from a trip where I exposed 400 sheets of film I need a way to do more than 3 sheets at a time.

I was thinking of using tubes with no end caps, vertically in a bucket. I figure I could bundle 9 tubes together and agitate vertically.

Is there anyone here using this method who can offer some guidance? Are there problems inherent with this type of agitation? What agitation schedule do you use?
