Grail on VV Reos Grand. Remove the o-ring in the well for air flow. Nice, tight draw, great vape. Because the juice comes up through the post, the first draw is a gurgle, but the second is perfect.
Edit: One comment: without the o-ring in the well, over-squonking will flood the juice onto the mod. I believe the 306 Grail has air holes in the side, so that Grail should work perfectly, since you can use it with the O-ring in the well. I find a single squonk should give about 12-15 good, long drags, so still fantastic as is.
