I use 100% VG and have gotten into the habit of taking some "dry" hits if I toke a couple times in a row. BCC works better with VG but even then I'll have to occasionally dry hit it to draw some liquid into the coil chamber quicker. iClear has a tighter draw than Protanks, which may be on purpose to provide more suction which is needed to pull liquid up the wicks better. Since Protanks are BCC their draw is looser, otherwise there'd be too much suction and you'd flood your coil.
ummm letting the pro2 soak for 20 mins....I do love the cleaning of the Pro2 as apposed to what I used to have to go through. Ok here we go...

Try keeping your wattage around 7W. I can run 7.5W with most juices, and a couple at 8W, without getting a burned taste.
