Get a Chromega drum, then. They don't leak.
I use 400ml liquid in the drum, and I have not had a single unevenly developed negative. The motor base rotation is pretty slow, and it reverses every one and a half turn.
I've used Efke PL50, Foma 400, Ilford FP4+, Ilford HP5+, Ilford Delta 100, and Kodak TXP. Developers have been Kodak Xtol, Ansco 130 print developer, and HC-110. 4x5 and 5x7 format. No 8x10.
