As for strong warmtone you can also try Harman Gloss Art Fibre Warmtone.
For natural warmtone, HmH Rag Baryta or Ilford Gold Fibre Gloss are worth trying and both of very high quality.
If you want to experiment Sihl Masterclass Satin Baryta has very analogue look, especially if you print directly B&W using QTR or similar. It is not easy paper but when you cope with it, results are unique.
As for MK papers, for warm smooth surface I use Sihl Masterclass Smooth Matt Cotton.
However, for me, Harman Gloss Baryta Warmtone is the best paper for B&W reproduction (if gloss is demanded or acceptable).
