Good afternoon GP Fam.
I stopped using a loop/U-wick design in my builds because it kept stealing more juice from one side than the other lol. I cut the top off now and it works great and even.
Thanks for the information! Funny you mention this.After the build I checked often for this (ocd) with no issue. I can see it happening though.
Your issue happens from either, inconsistent coil tension, individual ohms(meaning one is running a bit warmer, or wick medium.
I see it as just the opposite, the top loop will help ensure that there is equal juice to both sides.
Not sure if you were using 3mm hollow ecowool but, the wicking is superior imo. I have 4mm that is next on my list to build with.
As I clearly see the potential issue, I have had none what so ever but, will now think a bit more on it.
I can't get over the # of vapes I get from a fill @ 1.0 ohms.
