Has anybody shot Kentmere 200 between EI 250 and 400, and developed in Rodinal?

What are your impressions?

Until which EI does it work, and which Rodinal dilution did you try?

I am thinking about trying it at EI320 at dillution 1:25 for 8:30min with 3 inversions each minute

Trying to get some nice and obvious grain and making use of the mid-tone contrast that Kentmere 200 offers.
