I haven't tried either of those flavors from Mt. Baker, but I've been wondering about them. I've got pear, vanilla and cucumber mint juices from Mt. Baker at the moment. I can't tell if the cucumber mint tastes different this time around because I ordered a different volume and it needs to steep more, if there's been some kind of mistake in mixing it, or if the mint gets muted in my protank for some reason. Next time around I might get a little bottle of each of those to try out.
You guys should try the aerotank (or at least the base, as it works with the PT2 + 3). It basically is an adjustable valve that allows you to regulate how airy your draw is. The real win, though, is that it completely seals the connection with the battery, so no juice can get down there, which, I find, is the source of almost all gurgling.
