Vermouth question

I usually make manhattans with Noilly Prat, but a while back I picked up a bottle of Punt e Mes. Typically, I make mine with both sweet and dry vermouth, using a little more sweet than dry.

I've found that the Punt e Mes has a very different flavor, very herbal and bitter. Makes for a much-different drink than I'm used to. I'm almost tempted to not use bitters or just a tiny bit with this vermouth.

Just wondering what others think of this vermouth and if/how you adjust proportions when using it.
