To be honest, I have stopped using the SP-445 for any serious work.
    I am starting to come to that conclusion. I was looking at this https://www.bhphotovideo.com/c/produ...Film_Drum.html and I am considering going to tray development.

    It is a lot of work to get that annoying streak out. It must be the way the liquid enters and exits the tank or swirls around. I think for my next try with the tank, I am going to vigorously agitate for 1 minute, then agitate as usual. I also thought about semi stand to stand development as well after vigorous agitation.

    The options appear to be:
    1: Drum on manual roller,
    2: Drum on Jobo,
    3: Trays,
    4: Hangers, manual,
    5: Hangers, gas burst,
    7: Trays plus slosher.
    8: Brush development in trays,
    9: Beyond the Zone System tubes,
    10: Minimal Agitation in tubes, ala Steve Sherman.

    By far the cheapest is trays. It works very well with robust film. (It's not a good system for developing easily scratched film.)
    I use Jobo Expert drums with a CPP-2, but that route has gotten much more expensive than when I bought mine. BTZS tubes are a good choice for fairly small amounts of film.

    Like Peter, I use Expert Drums on the CPP-2 for "regular" film development. I do use a stainless steel Nikkor style 4x5 tank and tanks/hangers when doing minimal and/or stand development. As Peter suggests, I'd look into the BTZS tubes, but do a bit of research first because I've heard the newer black tubes (at least, for 8x10) can scratch the base side of the film. If you're doing 4x5, you may want to consider a Jobo 2509n reel for the 2500 series tank; cheaper than the Expert Drum and you would have the option to spin on a rotary base or inversion agitation.
