To me the difference in graininess is quite different. What do you guys think?

Mmmmmm Stefano sorry not helping me I'm affraid I'd suggest you shoot a whole roll of one picture with no other variations. Cut a few frames off at a time (in darkness of course) and try souping each length in different dilutions. That way you will be able to compare the results without any other distractions.
