I believe O-rings have been discontinued on Dunbar's. Dunno who came up with that brainstorm, but I coulda told 'em it wouldn't be practical in the real world. Probably some engineer talked them into it or the same goomer that thinks the joints should corked like clarinets and saxes.

I didn't mention their weight....

My preferred pipes are MacLellan's with bronze mounts and silver-clad tuning pins. They certainly aren't lightweight, and are on the heavy side. The P1's are close to the same. Delrin is a dense material.

As far as Soutar pipes, I have no experience and cannot advise either way.
