I have a Peterson D6 smooth (beautiful grain)church and love it. It has been a cool, dry smoker from the first bowl and exactly what I was looking for in a pipe like this. The bowl is a moderate size (dia .75", depth 1.54"). I find it works best with a good VaPer like Escudo.
I bought a 'rolled coil' of uncut pipe cleaners and made my own, saving $$$ and getting exactly the size needed. She passes the 'extended' pipe cleaner test easily.
The only downside, she is not really a traveler given her size. I do have a padded pistol case I use if I want to travel with her, but otherwise she is a home pipe.
Cheers. :
