So here's the scoop... I use delrin drip tips on 510 cartos - but only because I don't like the carto itself being in my mouth. Take a ProVari with extended battery cap, add a cartomizer, and then a drip tip - and it starts looking like the Empire State building... So I'm wondering if a "half-size" drip exists? Or is it something I would have to conjure up myself? Thanks.
