I tried this and it was allowing too much juice through the wick area. Gurgling and had to keep the liquid blown out of the tube from time to time. I also cleaned my wick and dry burned my coil at the same time so I must have not gotten the the two single strands placed back on top of the coil correctly. Touchy little things! I put it back to original design and now it works perfect.
Happened to me too. I think this happens with very light liquids. Darker thicker juices might benefit from it.
