Dokumol has been my only developer for a number of years. It is very hard working can give 1/2 grade increase in contrast, renders prints neutral in colour (even with the long lost Polywarmtone) and has, in my opinion, a particular 'look' that I have always liked.
With fibre paper (mixed at 1 + 6) it gives very deep blacks when you process for 3 minutes and will keep on darkening your image with no fogging up to at least 6 minutes (I have never used it longer than that and my standard developing times is 3 minutes plus draining off the developer). When the shared darkroom that I used to use closed down (the others didn't want to carry on with analogue photography) I was given some Eukobrom. I tried it and, whilst a perfectly serviceable developer, it didn't suit my way of working / print style. In my current darkroom I only have Dokumol.
Dokumol is not a 'special purpose' developer (just manufacturers hype) but rather a very robust developer that renders everything neutral so I would expect you would be very pleased with the results on the new cold-tone paper.
Let us know how you get on with it.
Bests,
