Just read this whole thread, as I've just had to address similar issues using some 70/30
@Dripworx juice (which is remarkably good in KF3)
All good advice, but I think I've pinned down a few variables.
1. Muji has changed. I have old and new now to compare. Once I worked things out I now prefer the new Muji. The trick is to borrow some tricks from the 'Scottish Roll' method. I split the pad in half. Stretch it so it's roughly twice as long as it was. Then use a rule of 1cm per mm if coil diameter (adjust to taste). Then loosely roll this with the flattened side on the inside of the roll.
2. One thing I learnt from the Gem is that you need to leave room for the cotton to swell. The pictures of
@bix_vapes' builds look quite stuffed in the channels. Once this swells it's likely to choke. I've found that with a 2.5mm coil it's just enough cotton to leave some room. With a 3mm coil you probably need to trim the tails slightly.
3. I found the whole 1 1/2 turns, 2 turns a bit crude. I also don't have a logo. So I've started counting juice control holes. I treat them like gears. If I getting a dryish hit, I turn it up one at a time. Gurgling, down one at a time. If you keep count then you have a repeatable setting. I found 70/30 is about 9/10 holes. 60/40 is happy at 7.
Hope that helps someone... My sweet spot us 1.5ohm, 2.5mm slightly spaced. But only because I'm using them on a couple of mods that won't go below 3.6v
