At Champs, early 2020 Las Vegas, phattpiggie gave me his personal stem..........The neatest thing about this one, besides it just looks exquisite, is that the stem is square not round..........With the square edges your fingers easily grip and spin without any slippage.
I can also operate it in my pocket without getting it out until it vibrates
I mean something that can come out of my pocket and giving me a hit or two pretty quickly and then back to my pocket
If I have to make it disappear it just goes back into the pocket.
I couldn’t decide when to stop quoting...The balls are so smooth plus they sit very freely (expansion) so I don't imagine I'll have issues. The worst I needed to do was "roll" some sticky balls out from where the ceramic bowl goes when it was really filthy. If you were shaking the stem around though that might not be a good idea.
