Apparently I'm in the minority but, I have the Zephyrus and the Billow 2. I hate my Billow. It's built great and the flavor is fantastic but the draw is just too tight for me, it actually annoys me because I know how much better it would be with more air. I'm use to the wide openness of the Zeph. I tried to dremel out some larger afc ring holes to make it better. I kind of worked but I scarred it up in the process. It's the black one too, still going for $37 on eciggity, should have traded it with someone before I dremeled it.
