I'm having second thoughts about my BTZS tubes. Using HP5+ at iso 400, I took two shots with my Crown Graphic and Kreuznach Xenar 135mm f4.7 lens. I developed the film in the tubes using distilled water and HC 110 Dilution B (1+31) from concentrate. One of the negatives had a dark band across it where I think the film overlapped just a bit. Other than that the negatives were good, albeit a bit grainy for my taste. I like the fact that I can just develop two sheets and use a small amount of developer, one shot no less. I have boxes and trays, I just wonder if it would just be better to use the trays and be done with these tubes. I'm just thinking out loud, don't know yet. I'm going to shoot two more sheets and try dilution A next. Any BTZS tube fans here or past users? I'm interested in opinions.

Humbly,
