Thanks for the suggestion, but I really don't see how thinking about that is going to help solve my problem! Lol.
It could if your problem is the atty drying out due to poor juice transfer from the cartridge. There is a reason why very few experienced vapers use this type of head. The reason is, because it sucks.
Also, I started out with a system that size. I found that very small batteries suck, because they are constantly going dead.
I recommend the CCV E-power system to new vapers because it's cheap, powerful and reliable. I have no interest in CCV whatsoever.
I don't think my problem is due to the nicotine content (because 11 mg/ml is not that high), so it might be due to the flavor. I guess I should experiment with different flavors.
True. You might want to try out a couple other vendors. Juice is very subjective. I get my juice from smokeforpennys.com, but some folks might not like theirs for one reason or another. I can't tell you what YOU are going to like or not like.
Also, you're saying that the only purpose of altering the PG / VG ratio is to alter the viscosity. But what's the purpose of altering the viscosity?
Juice viscosity plays a role in how fast the juice wicks into the atomizer/cartomizer.
