I'd probably have to say Clubman, because winters here in NW Boston are so long, and I can't be without it to get me through.
I've got several after shaves, including my beloved Clubman and the Veg, but since anything goes...I'd sure hate to be without my home brewed version of a bay rum. I call it Beo'wolf Bay Rum. No chuckles necessary, that couldn't be cornier!
