I think, also, a lot depends on the carver. One man's bulldog may be meh, while another's may be sublime. I'd try to find a shape that the carver is known for (last year's pipe is a perfect example).
Would I would like to see is perhaps going with a signature pipe by the maker. Along with the finish. Not really “I tried a new thing”.
If we have the carver nailed down then I’d opt for their bread and butter or ‘signature’ style
All of this. I think sticking with the carver's unique style and what they do best is the way to go. That should keeps costs within reason, provide a good example of the carver's niche, and be an all around nice LE.
