It's an obsession but it's pleasin'
is the OD of the glass tube the same size for the 7 and 8? I thought I saw someone mention it was larger on the 8.
I was told by Marc that the 7 uses a 5mm adapter and the 8 uses a 6mm. So idk if you can use the 7 adapter on the 8?
Sorry, forgot to mention that the 8 also comes with an extra pair of those small white pads that attach to the unit near the opening for the stem. They keep the stem from rattling around in there. My guess is you could attach those extra pads to the ones already in there and that would compensate for a smaller diameter tube such as one from a 7.
