I'm currently using an iStick 100w with the uwell crown on a .25 @ 44.4watts with suicide bunny mothers milk a high vg. After I get halfway thru the tank I start getting some serious spitting. I've been looking everywhere for info. The only thing I came up with was to unscrew the top piece. When I do so and break the seal a bunch of bubbles come up. So it seems that my coil isn't wicking properly. Has anybody else had this or a similar issue and if anybody has found a fix besides unscrewing please let me know. I would hate to have to do this every few puffs. Would going to a .5 ohm help at all. Other than that the Crown is an amazing tank. If only the holes on the coil were a little bigger to allow for a better wick. Thoughts on this would be greatly appreciated.
