I'm looking for a pipe with a wide bowl (.75 inches or bigger). I've read that they help aros and english blends burn better since it gets more oxygen and exposure.
Usually drying the blend is the biggest factor in helping those blends burn better. Smoking pipes lists the inside diameter for all the pipes they list on the site. Just clicking through the Savinellis everyone I looked at was > .75"
According to my amateur research, it's bowl shape that matters. So, the same width can smoke differently depending on the depth of the bowl. A prince typically has a squarish bowl where the bore is wide compared to its relative height which is shallow, a poker or billiard may be narrower relative to a deeper bore. Not sure if that makes sense or not...
For what it's worth, I have heard pot shape and prince shape are nice wide bowls.
i have a sweet Peterson 302, very big bowl, and a savinelli Hercules author, i also have peterson calabash, big and tall-as far as.more oxygen and exposure. i believe that would depend on the packing, .not size of the bowl
Burn better? I don't know about that. Some blends burn better for me in certain pipes than others...shape of the chamber doesn't seem to impact that at all for me, though. It has more to do with the cut of the tobacco and it's moisture content, as far as I can tell. But wide bowls are great, and if they work well for you they can burn nice and cool and offer a different take on a blend. Princes as Savinelli turns them out are pretty wide and shallow on the whole - I have one of theirs and love it, but it doesn't seem any better for latakia or aromatics in particular than any other pipe I have. A more traditionally British prince may be a little less stocky...and still a great pipe if well made!
