ANd quigs, thank you for the reply. I recall your issues with yarn taste and what not.
I was just under the impression that Line/Single Vertical Wick systems "needed" an open straw type set up to wick well, all those videos make a big deal about keeping the center channel of the SS mesh open.
for mesh definitely, especially if the device doesn't have a vent hole...but Lines do...good point though, not sure how cotton wicking would be effected if there was no vent hole, about the same I would imagine, sooner or later a vacuum will build if air can't replace the juice being wicked out, it wouldn't matter how good the media is at wicking, hmmmm...
