mrhemi71, can't speak for the Kaywoodies or Yello-bowls, but I've got a cheap Medico Conq. bent billiard which smokes great - a touch of gurgle with some of the goopier aromatics, but otherwise, I'm happy with 'er.
I'm sure it could be pushed like true meer, but since its just an insert in briar (well, fills - it is YB we're talking about after all!), I rest her just like my other pieces; after all, I've got enough pipes that I don't need to smoke 'em back to back to back.Schmitzbitz: the meer liner you speak of does it function just like smoking a meer? Very little rest between bowls (wait for it too cool down first).
