This has been up for two days and no one has idea's for you? Well i got some, but you are going to need a few more pieces of equipment so as it looks a bit better.
Now are you talking about the one with chrome end caps? I am asking as this is the idea i have for it....
Get yourself a ego to 510 adapter (the ones "made" for provari, they have the centre 'vent' hole). Put the adapter on the lava tube. Now around the ego threading add a stainless steel shorty cone (either round our flanged). Add the tank. If when snug it is too tight to no draw, then unscrew it, and as you dry draw (without pressing the fire button) screw it into the connector slowly. You should get it to where the tank is a hair line turn past were it might wobble on the adapter and this will give a better overall draw. Yes i know it might seem to light, but one thing i found is it does not come down to long wicks or short wicks, but how much air gets into the tank that effects your throat hit and flavor (as well as certain drip tips)
Now if you excuse me the Caffine gods call me and i must obey
i hope this was helpful and let me know if it is
