Ok so it sounds like the website was not updated at Mt. baker to reflect the change in wick material for the nautilus mini. The more I learn the more confused I get because it just opens a whole other can of worms-questions I have. Lol. All I've used are the silica wicks that are in my kanger coils for my evods and protanks so I have no clue about what would work better for me. I will get to experiment with that next week!
Mt Baker Vapor just hasn't updated their website. I can assure you that you'll get the tank with cotton coils.
Compared to the Silica wicks you'll find the Nautilus cotton coils give MUCH better flavor. However, before you use them I recommend dropping 3-4 drops of juice directly into the top of the coil and then apply a small amount of juice to each of the wicking holes on the side. Then install it into your filled tank and give it around 10 minutes or so soaking time before you start using it. When you're ready to use it take 2 or 3 puffs without pressing the fire button on your mod to make sure you've sucked enough juice into the wicks and they are fully saturated.
After that it should work great. I use the full sized Nautilus as my tank I take to work. My boss lets me vape in my office, but wants me to keep it low key. No subohming and no strong smelling juices. The Nautilus works great for me for that purpose, and yet it can still put out some impressive sized vapor clouds.
I'll bet you Evods never did this...
