I find the recurve has better flavour over the drop solo, but the drop solo is better at dripping. Recurve is almost squonk only.
If you vapor you need to take advantage of the dual 18650 and go dual coil. Drop, Drop Dead, or Dead Rabbit all work - best is up to preference.
I'll look at what else they have. Right now, for me, the Kali V2 and Goon 25 are kings of the dual coil segment.
Edit: They have all 3. The thing I like more about the Dead Rabbit is that you can squonk up to the
coils without leaking. More saturation is more flavour in my experince. The Drop Dead will allow the same, with some added features like a locking cap so you can twist it off. For squonking i'd go drop dead.
