I've been vaping now for about 2 years, I've been all rebuildable for over a year now. So far I have been using braided silica, but the B&M I got it from stopped carrying it. I found some online so I stocked up, but this new stuff is awful. It lasts half as long, if that, and the silica taste that usually goes away in a few hours never goes away. It also doesn't wick as fast. I got so frustrated with it that today I pulled the wick out and fed a cotton ball through the same coil. This far I've been enjoying the hell out of this, I just need to get out of the habit of drying my wicks out, and figure out how to build a coil without the wick.
