Hi Marianne,
I would maybe suggest using the fomabrom variant IV first to see how it compares...you might like it. I haven't used that particular paper, so can't help you there, but I've had the most success with the Foma MG papers (131, 132, 542, 532). However, my prints have a lot more colour than yours do (that being said, I haven't had a chance to tone mine yet, so am not sure of the differences between toned and untoned). My avatar picture is a good example of a SE5 and Foma 132 combination (high dilution and warm developer combo).
(sorry, at the moment I don't have access to my scanner, so can't scan some of my other prints to show the effect better).
Actually, you might try this (there was a url link here which no longer exists) on page 22 for a couple of other examples: the first post is the old 542 chamois and SE5, the second is 132 and SE5. Most of my dilutions run between 1+25 and 1+35.
