For the Nano I have the wick tight in the coil body (I can feel pressure sliding it, though it doesn't deform my twisted 26AWG), The tails I pretty much just chop 50% off of (the upper part of the tails). I then cut length so that when the tail is folded down to the liquid ports it is just barely inside them (so the ports hold the tails in place if the tank gets knocked around a bit) That means the inner edge of the tails will actually be a bit deeper into the wells, but I'm too lazy to really cut them even [emoji3]
For muted flavor you may need to adjust positioning. I use 2.5mm ID, twisted 26. For me I have the center of the coil body even with the middle of the posts (coil center at midpoint between the two grub screw holes). I then horizontally center the coil so the tails will drop directly down into the two
eliquid holes. Other people get good results positioning the coil a bit higher vertically -- there's a little trial and error depending on your particular coil.
Once you get the coil positioning straight for your coil, it really is an excellent flavor tank [emoji106]
