why don't you go to sprint ?
and get your chems drop shipped to you ( or through b&h )
they are good, developers, fix stop, fix remover
they all mix 1:9 ( 1 pt chems 9pts water ).
and work with every film made today ( and yesterday )
and they have a chart to help you determine the best development times
for your film, and situation ( plastic lens, old film, &c )
a LOT of schools use these chemicals because they are FOOLPROOF
i used them for a long time, and still use them ( film dev and fix ) ...
if you use their print developer too,
you use the chemicals over and over again, until
the fixer indicates and it tells you IT IS ALL spent, not just
the stop bath ( that is the sprint "system" )
good luck !
