Most often my pipe rotation is like this:
Day 1: Kirsten
Day 2: pipe A
Day 3: Kirsten
Day 4: pipe B
Repeat

So the conventional briars (pipes A and B) get 3 days of rest between smokes. And they rest near a door that's open year round (at least during daytime). Mild climate in San Diego. The pipe A and B selections tend to remain the same for several weeks.

But sometimes I smoke the metal-stem Kirsten every day, all day. I consider it to be the best-smoking pipe I own, even though it's the least expensive pipe I own (except for $5 cobs that I have on hand for friends to use).
