@vapirtoo . What can I say, I've been enjoying my new vape. ? for ya. How does the thickness compare between the AIWB & the straight glass stem. Would be cool to have a little bit longer vapor path & a carb for direct draw. Been sticking all kinds of stems in the Supreme (some worked, some didn't) & am finding the thicker the glass, the more restricted the draw. Figured I'd ask you b4 shelling out $20. The thickness of the straight glass stems are just about perfect for me. Edit: Just ordered the AIWB. We'll see how it goes. I think I got SAAS. Supreme Accessories Acquisition Syndrome! @Tommy10 It should come w/ a red & white grommet/seal. Stick the white one over the end of the aluminum tube to make a seal w/ an 18mm female joint. Instead of using just the red one for 14mm females, use the trick @Buildozer suggested a page back. Put the white grommet on 1st, then the red grommet on after. Using the red 14mm seal by itself makes it a PIA putting it in & taking it out. Using both, it just sits right on top of the 14mm F joint. 100% better experience.
