I just received my new vulcanized freehand stem for my legend from Aristocob. When I got it, there was a little bit of extra material I needed to sand off near the mouthpiece so it wasn't so sharp. Not a big deal for me. I ran pipe cleaners through it and cleaned it up after wards. However, the stem seems to taste funky. Do they need too be broken in like a pipe? Is it just how that material tastes? Any suggestions?
