that should be very good, I have always used the cvs sterile balls, not rolled, but they should be similar. so it shouldn't be the cotton. as for the coil, your 28g at 1.8mm seems like a great set up at 1.5Ω although 2.0mm could be a little more forgiving. for my vv/vw set up in the provari I do find 2.0mm to be a little more consistent with wicking. with that said though the set up you do have should be fine and as long as your coil is fairly tight and lighting up from the center out then you shouldn't have issues with the actual coil. one last question, do you run a straight coil or is it like on a 45 degree angle? when I first bought the first kayfun, I followed the svmesto recommendation of doing the coil at a 45 degree angle, this allows for the wick tails to be placed along the ledge compared to straight down like in the straight coil orientation. I have done both, straight and angled and both work fine but if I had to just use one configuration based on consistency, I would have to say the angled coil is better imo. for me, with my variables I always had less issues whenever my wick tails laid sort of across the deck ledge compared to just straight down. now believe me, I had many straight coils and straight down wicks and they have worked great but not quite as consistent as an angled coil. also maybe its assuring to know that when I do place my wick tails sort of across on the ledge, I know they are there to stay and cannot move. I know if one has a straight down wick tail that just reaches the ledge, chances are it also will not move, but there is a better chance that it could move slightly by the juice possible coming onto the ledge and pushing up on them a little, or by the device being laid down or being knocked around, or even being sucked upwards from heavy vaping lungs. believe me, I have no idea this could or has happened but I just feel like if the wicks are trapped the way I do it, this possible scenario is less likely to occur. have you tried another juice in it to see if it could possibly be the juice? I do have a couple of juices that just don't taste very good in the kayfun lite pluses. its mainly 2 strawberry vapes out of many many juices that I have vaped in the kayfun and for some reason they just taste like crap. here is a pic of how my coil looks like before its saturated. for me anyways, I have always tried to error on the slightly more then slightly less thinking on the amounts of cotton. after knowing the best placement of my wick tails there is either not enough, or to much cotton, for me It usually works that not enough cotton I get a prolonged sizzle after releasing the fire button, followed by dry hits, if to much cotton, I get a sort of nasty muted cottony taste. what I try to accomplish is having just enough cotton that I don't get that crap taste rather then trying to make my coil just big enough as to not get dry hits. and of coarse after I saturate the wick tails, I then kind of push them over so they touch the side of the ledge.
