Drilled out the holes, exterior and interior, as well as opening up the four slots on the battery connector (with a jeweler's file).
Hi sjohnson...could you post some pics of that, maybe some tips on how you did it?!
I can't seem to get a better sensation going directly into lungs. I only get a decent throat hit when I build up as much as I possibly can into my mouth and then inhale it. True, on the direct drag I get a lot more vapor, but not nearly as much sensation. Currently I'm using a 4th gen 510 with the standard battery.
