I did not read this entire thread so not sure if it has been mentioned. I use the T3s and the trick is to remove the little silicone cup that sits on the air tube just above the wicks. You will get much better wicking and no dry hits. I have heard some folks that use 100% VG say that they also remove one of the wicks and it wicks great with 100% VG but, I have not had to do that myself.
Good luck and hang in there!
