I used this paper a lot, and even still have a pack of it in the fridge.
I am very rusty on my darkroom skills, but you're experiencing the typical novice problem with contrasty negatives. What you should do is spread your print exposure into three: one for the shadows, another for the highlights, and then another one without any filters at all.
I forgot exactly what the sequence is, but let's say it's something like this: if your total exposure is going to be 10 seconds, then expose about four seconds without a single filter; then about three seconds with a #4 filter (it's magenta), then about three seconds with a #1.5 or #1 filter (it's yellow).
I did this with much success (if this is the right sequence; it was about two or three years ago since I last stepped into a darkroom) when trying to bring out both highlight and shadow details with "problematic" negatives. I recommend you do your own tests yourself.
It all depends on your negative and how much detail you can and want out of the highlights and/or shadows.
I hope somebody with current knowledge of darkroom printing techniques can chime in or correct/add to what I've said. But that's the basic idea.
You're basically doing the analog version of tweaking "curves" on different layers and merging on Photoshop, if you need to understand that way, what you're doing with this method.
