My lemo 2 gets no love. It's airy, but flavor is non existent. If you want to Chuck clouds with a tank, the lemo can, but you'll only taste about 50% or less of the flavor in the juice. Now, that might be my fault. I never tried dual Coils. I never saw a need for duals. The only two dual coil tanks I've used have been a fogger v4 and aqua (v1?). Both were ok for their respective times, but would feel choked off based on today's open draw standards imho.
I drilled out the post in my k4 and 2 of the air inlets in the stem. It helped some but it's still a MTL atty. My favorite go to atty has to be my Taifun gt2. I slotted out the air intakes, while I'm sure it had to improved air "some", it was barely noticeable to me compared to the stock 5 holes (or 6 holes whatever they were).
I was considering the crown by u well, the tfv4, and possibly even the subtank mini. BUT I'm a rebuildable guy, not a coil guy. I generally rewick (at least) or rebuild the whole thing after 2 no more than 3 tanks. The juices I vape are gunkers, so can't really push them much farther because of the crud build up on the Coils. And now since I've embraced temp control in a love/hate relationship rewicking means recoiling too since the wire is so soft.
I hate to get the crown, tfv4, subtank, etc and end up as disappointed in any of them as I was with the lemo 2.
I saw it mentioned to try the lemo 2 with dual Coils, I can do that and see if that helps.
Thanks for all the chatter in here, please continue... I am reading and liking all your posts! Thanks again!
