For me it would have to be schmalzlers. They have enough complexity going on already and tinkering with them would only do more damage than good. What about yours?

Any old mill snuff.

( I mix some schmalzers and use the plain ones as bases,  because they have too much paraffin with which my nose just doesnt agree too much.

I would never make the sacrilege of mixing SWS, Abraxas or Molens. Self-explanatory.

SWS, Abraxas, Molens are any artisan snuff

I’ll happily mix any snuffs.

I too will mix almost anything at least once. And as far as mixing scmalzlers my suggestion is to only add a tiny amount of other snuff. The results can be really almost alchemical in expressed scent.
