Anybody has any suggestion on this one? I did a lot of search on this forum, but just got few answers. Seemed like not a lot people using this combination.

I am asking this is because I want to try to do some experiment with FP4+ film to see if it's works better in xtol than in Rodinal (I am using 1:50 rodinal).
Rodinal is fine to me but the grain is just a little bit more than I expected.

I am planning to shoot FP4+ at ISO 160, so, any suggestion for how to use xtol, like developing time, working concentration, etc...

I am using 35mm format.

Thanks in advance.
