Protank has a lot to recommend it, but maybe it's not for folks who won't tinker. If it isn't wicking enough with a thick juice you prefer, remove a top wick. If it gurgles, add a tuft of cotton or a thin silica on top. If the draw is too loose, plug a hole or two. No biggie.
I prefer a very tight draw but on top wick clearos with a tight draw, loosening them up is a real project. It's a lot easier to tighten a loose draw than to loosen a too tight draw.
