i don't have experience with ryuji suzuki's photo chemicals
but i am sure they work well.

for years i used the sprint system of chemistry
metol free developer, d76-esque but better/different, vanilla scented stop, high capacity rapid fix
easy to mix, stores well, good stuff ...
and if you use the whole "system" ( dev/stop/fix ) when the stop indicates ( turns color )
it is time to mix new everything ...simple ...
