Dumb question time. Any way to stop the chimneys also coming out of the boro when you unscrew the 510?
Ah... I haven't seen that since the SXK Kanger bridge. With JMK Tips that never happens. Wait, don't buy them, because if you don't like SS tips or the bridge doesn't actually reach the top of the boro, they're useless. But what they do have is no o-ring meeting the bridge. And that is my advice, take the o-ring off of your nut or hybrid drip tip and you are good to go.
I first thought this was a bad idea, but it actually works out well. I never notice the difference besides if anything less condensing behind the boro. And the bridge doesn't pull out of the top.
