Permawash? or Stop?

I don't use XTOL - use LC29 at 1:19 one shot. Fixer and stop I mix up in 500ml at a time and throw when exhausted. I check fixer with the snipped off ends of the 35mm film. I mix all fixer at 1:4 and use the same mix for both film and paper, and the same stop. (don't know whether this is good practice, but works for me). Photoflo I use one shot. I have it ready diluted so I use a film can/film which makes measuring easy. (It's not actually photoflo - I use "johnsons photographic wetting agent", but they went out of business years ago)
