Anybody ever tried these modern IR films in Diafine? I have some Rollei in the freezer, the R72 filter, and plan to give that a go this spring, mainly because there's no guess work about time and temperature, same for all films and it does what it's going to do. It gets a bit of extra speed from some films so we'll see if that helps with these films.

If the first roll is awful I'll go to conventional developers.
