I've read most of this thread and all i can say is WOW, that's a lot of info. I've learned that i need to roll my wicks solid to wick better, it has worked for me with the 400 i had left and the cheap stuff that came with my DUD. I rolled the first 2 hollow or what i thought was solid and had to trim them to get them to fit, my sister bought one and I then rolled those wicks very tight. They worked rather well compared to the stock wicks i had trimmed, they even let me vape with the fill screw in almost never a dry hit!!.
That being said I finally got some #500 from stormys and found that I just cant seem to get this stuff to wick at all, ive tried rolling it as solid as i possibly can, I've tried juice burning, ive tried without juice burning (my coils are going surprisingly well for me) but i just cant get these wicks to supply the juice short of tipping them upside down (i also test with the fill screw out to make sure thats not my issue) ......
There has got to be something im missing or doing wrong, the juice is just not climbing the wick. I know it can be done because ive had it working before where i could do 25 second vertical burns before id have to let it wick for 1-3 seconds.
