It's been proven with food that presentation can improve the taste of food. That sometimes eating the same thing on the good china will taste better then if you use paper plates. It's not a definite thing but enjoying something isn't just a flat experience it's not just the food in your mouth or the smoke, sometimes for some people seeing it on something fancy tells the brain pay attention this is special. So it stands to reason that an expensive fancy pipe could smoke better without physically changing a single characteristic of the smoke. Just something I was thinking about while enjoying one of my pipes. It's not a promise that if you find a pipe special that you'll have a better smoke but there is a very real chance that it will, because you're a human and we have these weird complex brains that we don't even really understand all that well.
