I use Shiseido cotton.
Got what's probably a lifetime supply during a short period when you couldn't find any KGD, and I like it.  I have tried to like XWick several times, but I don't.
I think I know what's happening - as I rewick when I sense a degardation in flavor, and sometimes that's a day, but sometimes it's a couple weeks.
And the difference has to do with "scorching" - if your wick it tight and/or you vape it a little too dry, you can scorch your wick.  Just a little.  A good squonk will return you to a good vape - but you've scorched the wick.  When you change it - it's dark right at the coil - scorched, right?
You could try using a little LESS wick - so it's easier to keep wet inside the coil.  And you said you're bottom-feeding, so squonk a little more frequently!
Wetter wick will last longer.
On the other hand - I DO think that there's a future fad possible if someone crafts a good wickless squonker.  I mean, you COULD squonk every hit and vape without wick probably.  What if it was better than that?  A tiny pool that touches the coil?  A coil that holds 3 hits of juice anyway?  An "auto-squonker" that rejuices itself after every hit?  Who knows - but I wouldn't be surprised, and might consider trying one!
	
		
	
	
		
		
			yeah, starts to taste a bit burnt after 6mls. not terrible but bad enough for me to be rewicking every 6mls. after 9mls it's not good at all.
i just can't figure this out and it's driving me mental.
i think the only two things i haven't done are: try without sweetener (doubt this is the culprit because 0.5% of sucralose isn't a lot), try ream the small stock air hole on this atty to be bigger.
that or try rayon or something. only ever tried KGD and RxW.
anyway
