Maybe I missed it, but I'm surprised nobody asked you what kind of battery you have/prefer?
I have an auth Tugboat V2, and I really like it in a mech (black copper stingray clone). Maybe not conducive to twisted builds though. Airflow and flavor is okay - nothing to die for imo.
Tobeco plumeveil 1.2 was a hallmark for flavor for me for a while. Do not order one with gold plating - mine flaked off... The infinite clones from eciggity have been reccomended to me. The airflow limits wattage to about 70 (regulated) for me - don't care for "vacuum" delrin air option at all, it just melted...
Honestly, mutation x V2 on a mech (.22ohm) was underwhelming and flavorless. 87w on a 100W box mod has proven to be the best of both worlds for my tastes. However, I have noticed that I had to adjust the flavor strength of my juice to fit the heat and production. I also like the shared juice wells. Haven't tried the V1 - but the V3 just came out and has extra perc of 510 delrin drip tip adapter.
Ive been building for about 8-9 months and I've also really come to like a dual center post hole (i.e. T block). I find that my lead lengths are much more precise between dual coils bc I can secure them independently. Also the MX V3 did away with the odd screws (triangle I believe) and replaced them with phillips.
18650 mech - plume/tugboat v2
100W+ box - MX V2 or V3
I do wanna try the vertex as well. Hope this adds to your productive confusion!
