So after a lot of trial and error, I seem to have figured all the various tricks with this tank:
First,
the tank... QA on this tank it seems is excellent regardless of the online source. The tank seems to have impeccable construction and works flawlessly. Fill it to the brim (I'll get to that in a sec) with your favorite flavors of any consistency and it will vape amazingly well, dare I say the best bottom coil vape you will get. (Aside from building your own)
Heads: these are really where everyone's issues lay. Seems that on average most owners are getting bad atomizer heads right out of the box. This was my biggest issue, and this isn't just exclusive to the heads that ship with the device... Replacement heads are hit and miss as well. I am guesstimating that about 30% of the heads I have received, and I have ordered a total of 40 heads (not to include those that shipped with the five devices I tried), were completely faulty duds out of the box. Three of the heads kept giving me an "atomizer short" message on my EVIC right out of the box. 10-15 of the heads I ordered as replacements would not function properly, either from dry hits and a complete lack of wicking, or burning out completely before even finishing a tank. Lack of wicking was the problem I ran into the most however, and when it happened...
no amount of "switching to more PG" or "filling to half" would completely remedy it. A bad head is a bad head, and if you are having to fill your Nautilus half way to get anything resembling flavor, you have yourself a bad head friends. The heads that would burn out quickly (before finishing the first tank on that head) would do so
regardless of PG/VG combination, or dark/light differences. Cleaning with 192F water and/or Everclear did not remedy quickly burning heads.. a few puffs, and they were doneskies.
However, when I got heads the worked correctly (25 or so out of 40) this was one amazing vape. Regardless of color or consistency, with properly working atomizer heads the Nautilus performed flawlessly. If you have a properly working head, you can simply fill it to the brim and vape to your heart's content. I typically went two and half to three tanks per head before cleaning in hot water (everclear for the darker vapes) and after cleaning it just kept going. Due to my wanting to test all the heads I ordered, I only went through cleaning twice before switching to another head (and with the cleaned head still working).
Summary: Heads are the issue. If you are having to fill your tanks half way for proper flavor (or any for that matter) or you are having trouble with certain juices. You are attempting to use a bad atomizer head. If your atomizer head burns out before even finishing a tank of liquid, regardless of consistency or color (and especially if it is high PG light colored) you have a bad coil head. You also should not have to take a few priming puffs every so often unless you are running a thicker liquid and/or using the 2 largest air holes. If you are constantly having to suck on your Nautilus like it is going to pay you when you're done, you have a bad atomizer head. Apparently Aspire has done absolutely horrible QA/QC with these atomizer heads.. and this is the one (very major) downfall of the Aspire Nautilus
The suppliers I ordered from: No supplier showed a trend towards shipping more bad heads than the others.

This wasn't exactly a strict scientific testing regimen, but an effort from myself on trying to figure out the issues plaguing myself and my fellow Aspire Nautilus owners, and from what I have experienced first hand as well as from experiences of other users on this forum and a few other locals that I know personally... the constant issue is the atomizer heads. Some people get lucky and get mostly good atomizer heads, some are having horrible luck and have yet to find one that is working properly... most are in the same boat as me (as far as I can tell) - about a quarter to a third of all atomizer heads we are receiving are crap.
Hope this helps inform other owners and prospective owners, and BTW... Boba's Bounty is AMAZING in this device with a working head
