Before I bought my Jobo CPP-2, I used homemade BTZS tubes for 8x10 and
4x5.  While 4x5 worked ok, the 8x10 tubes did not.  They were too
heavy and bulky.  I found it very difficult to keep more than just a
couple agitating properly.  But if I only want to do two at a time,
why not simply use two trays, or even more?  With only one sheet in a
tray, there is no scratching.  Sure, it's less efficient with
chemicals, but then you can use very cheap developers like D23,
Ryuji's developers, or Patrick Gainer's formulas.
