So, I'm a couple of months into my original coil T3 and have only one complaint. The flavor wicks. I've done 2-3 thorough cleaning/dry burns. The first time, I tried (and failed) to capture and reassemble the wicks. Fruitless endeavor. I tried various combinations of 1, 1.5 and 2mm diameter replacements and found a single piece of 1.5 or 2mm to work very well. I'll give a slight edge to the 2mm in vapor production and taste. So in the future, the flavor wicks are going to get tossed and replaced with 2mm from day one. Since it's so easy to replace these wicks during the dry burn cleaning process, I start with fresh wick after every thorough cleaning. Also, I've found that the inverted silicone seal trick helps a great deal and has resulted in no dry hits, gurgles or leakers. For whatever reason, the 2mm wick has solved the gurgling problem I had with the OE flavor wicks. YMMV, but this is what has worked for me.
