I bought a hunter stem and a couple of bowls a few months back as a fishing pipe. To say I was impressed is an understatement
Cons
They're ugly and I mean real ugly, the matt black hunter stems help the looks but they're still ugly,
they're the nastiest pipe in the whole wide world to break in,
I need to carry special pipe cleaners and a pocket of tissue just to clean the pipe
and they do feel a little cheap.
Pros
They smoke incredibly well and smoke drier than a regular briar pipe,
Cheap - at least in the UK,
very light and easy to clench,
a single stem and a handful of bowls is more portable than a handful of pipes and cheaper,
buying bowls is cheaper than buying pipes,
stems don't ghost,
metal stem makes them a tough little pipe
and they smoke incredibly well and smoke drier than a regular briar pipe!
