yes. tar build up bad. color build up good. glass with the chemically changing schemes are, in my opinion, Very sweet, the best. For a pipe, i would go with something small cuz i want it with me so i don't want to deal with glass on glass for my pipe. all about what YOU want, stop asking us and go get one for YOU
just make sure you're gonna really like the one you pick:thumbsup:
happy hunting:thumbsup:,
Peace:rasta:
