Some pipes—no idea what percentage—require no break-in. They smoke perfectly from the first bowl. I miss the taste that raw high-quality briar imparts to the first few smokes before the pipe is "broken-in."
Not a priority, but a sitter is very convenient when you want to put a half-smoked pipe down in some random place or your pipe rest is in use with the pipe you're smoking and you want a second pipe on standby ready to go.
Sorry, @Medy, I was just making a lame joke. You said you were smoking sweat tea. I assume you meant you were smoking sweet tea, which actually sounds like it would taste pretty good. Welcome to the forum by the way.
