Exactly! That's the first thing I noticed about longer stems, is how much cooler they smoked. I still catch myself getting after it and smoking too fast at times, but it's way more noticeable when I do that, with a shorter stem.
Flavors are much more pronounced with longer stems for me. My favorite cob so far is the Dune Cobbit. That wide, short chamber with the longer stem, is fantastic!
That's the main reason I bought all those cobs, was so I could start experimenting with chamber sizes and stem lengths and find what works best for me, before I start buying more expensive briar pipes.
It's interesting how different pipes can make the same tobacco taste and smoke different.
