Where did you place the coil in relation to the posts? In the middle or closer to the top of the posts? Gathering tips before I build mine.
Thanks! Enjoy!
I lucked out, ran across it when I first started building. I had bad results with cotton, turns out I was packing it too tight, but perfect for rayon [emoji3]
You're missing out if not. The flavor is better because the wick transports better/more juice to the coil. You can hear the difference as it's cooled down more by liquid, so generally one needs a slight bump of power to make up, compared to cotton. Cotton is great though, but rayon just slightly edges it out imho. I don't pack it as tight as others, and just slightly more than cotton, but not much... Get e.g. a pack of rayon-balls if wanting to test it without buying the bigger lifetime-bags. I use tidi balls myself as having a hard time finding the graham big boxes locally, and shipping kills it for me.
It's the opposite here the giant boxes of Sally's Beauty Graham Cellucotton (rayon) is pretty cheap. I got a bag of Delasco's 100% rayon balls as suggested by @JeremyR and it was relatively more expensive than the giant box. Couldn't find the Tidi as it was recommended as better than the Graham's.
You definitely should! Check out the thread here @JeremyR rayon wick, better flow, flavor, longevity & nic hit.
Rayon or cotton should not make much of a difference. The only difference between them is the amount of wick in the coil. Less for cotton and more for Rayon in the coil.
By normal vaping motion(tilting), and only when the tank is almost empty, as else there's no issue as the liquid goes under the base and up to the holes where the wick is, like kayfun v5, ammit, boreas etc etc. Think e.g. the limitless/avocado and likewise RDTAs where many just cut the wick a little under the top and still OK. Note, not saying it's wrong to wick like you at all
I did notice that in the suckmymod review of this tank, then he stated it was important to not let the tails touch the bottom. I don't know why he stated that, as I wouldn't think that would be an issue either, just maybe not needed. I haven't tried wicking to the bottom myself yet, but generally go for shortest amount necesary. 
The bottom line is if it works for you then keep up the good work. The Engines are a forgiving atty.
