Thanks, bookmarked for when I next have thyme on hand!
The other day I tried this Maurice (rye, Cocchi Americano, Sauvage, and a little Antica) which is likewise mentioned on the Bittermens site, and which is more in the Manhattan/Brooklyn mold. Or I suppose you could call it a White-ish Boulevardier. There the gentian was a nice "complexifier" rather than hogging the spotlight.
