So my ego type A & B drip tips arrived today and they are a perfect fit in the A2-T and A2-MT. So here are the working theories on dripping so far:
1) Remove wick plate from center section and drip away.
2) Drill very small hole in upper A2-T or A2-MT section to be able to drip without needing center section. It appears that a hole at the very top edge of the bottom coil section threads would work well and not allow too much leaking from over dripping.
3) If you are careful with your drip there is no need to drill a hole in your A2-T and A2-MT top sections, all you have to do to get airflow is unscrew the top section 1/8 -1/4 turn and you're good to vape your brains out. It's also smaller that when using the center section and looks a bit cooler to me as well.
Also if you make your coils traditional A2 style push the wick down around the bottom of the coil to soak up excess drippage and no leaks unless you squirt in the juice. And if you really want to play it safe stick some extra wick down around the coil posts too and you can get 20 or 30 drops in there without leaking.
Hey wind with all your drilling and messing around is there a way to use this with our bottom feeders.
