Ok, but so we are on the same playing field, are you lung hitting? What wattage level? Tell us about your build and wicking. Comments about performance can be very subjective without enough info.
For example: If you're chain vaping max VG at 35-40w on the largest airflow setting with no probs I would like to know how you're getting there!
3mm ID. 24 gauge, 5 wraps, ~0.5 ohms, Japanese cotton. Fairly standard/simple. I generally stay between 20-25 watts on regulated but I do use a mech sometimes (just take it a little easier with the mech). I just rewicked, this is what I start with:
Then I trim it down just a bit, but not much. I try to essentially fill all of the free space on both ends, then just take a little screwdriver or something and push it back in the center so that the juice channel on each side is nice and exposed.
I chain vape when I'm home but my chain vaping may not be as extreme as others. To me chain vaping means the equivalent of chain smoking cigarettes (like lighting one up once every 20 minutes) -- I am consistently hitting it but I do take a bit of time between puffs, whether it be 10 seconds or a few minutes. I generally take about 4 second puffs.
I'm no expert, in fact this was my first rebuildable and I'm only like 2 months in -- but this suits me just fine. I don't get dry hits, I only need primer pulls if I'm really power hitting it without pauses, and I have zero leakage.
