I just bought a Walker Briar Works Forever Stem for my MM Pony. I got an 8 inch vulcanite churchwarden stem for it. My Pony is my favorite cob, and it can get hot easily if you aren't careful. I figured the longer stem will help keep the smoke cool if I start puffing too eagerly. Plus I've wanted a churchwarden for a long time. I'm happy I got one finally, and they're from Michigan. So I'm supporting a Michigan business. I also got a stem for my MM Legend, but it wasn't from Walker Briar Works. I had a thread on it here.
