I dunno, my 510 gives me a pretty good throat hit with most liquids. I've noticed that when I mix with VG it goes down a lot. I've never really understood why some PVs give better throat hits than others, I always correlated it to being the volume of vapor plus the ingredients to the vapor itself. I guess we could also factor in the heat of the vapor, but honestly it doesn't seem to get super heated to the point where you would notice a huge difference.
Perhaps the Blu provides a good throat hit, hell perhaps the wick on the blue you are vaping from is burning out and you are getting a good hit off fiberglass![]()
At anyrate, now you made me want to try out the Blu.
Il second that ... those Polyfill can burn and give you a massive throat hit like you are smoking an analog .
