I group my dedicated pipes into like flavor categories. I greatly prefer lighter flavored aros, and I have 6 aromatic pipes, with 2 for caramel/butterscotch flavors, one for vanilla, and one for anything fruity. I make an exception for Rattray’s Exotic Orange, which gets its own pipe, and for Lakelands which get their own pipe. I use cobs for anything really heavily flavored, but seldom smoke those.
