I agree with the posts above, beeswax...I have an estate meer to restore that I haven't touched yet, but I'll be using beeswax for it.
Just a personal observation, I actually like Halcyon II on smooth briars as well. I just tried it recently, worked pretty good. I may just order Halcyon II alone going forward. Although I do like Paragon, most of my pipes aren't smooth anyways...
