Hi Jay - no, I don't think grinding or hit length is comparable to theoretical physics but if you look over the long list of posts in this thread, it seems obvious to me that people are proposing all sorts of body English in how to use this thing to compensate for what appears to be either design or unit manufacturing defects. People have been told to try this, try that, try it all while standing on your head, etc, etc, etc.
My question to any of these FF supporters is this: would you accept this level of finickiness in a $300 coffee pot? I suspect that NO, you would not and vaporizer are home and personal appliances in the final analysis. IT SHOULD JUST WORK....otherwise the designer didn't do a proper job IMO.
I'm not out to bash FF and really, really want FF2 to be successful as I want either an FF2 or a GH to compliment my Volcano and wax box mod & pens. But I do find FF's rebuffing of people with air path issues to be....well, let's just say that they have not earned my respect with their approach and communications on the subject.
I'm going to stop now as the more I defend my views the more it would appear that I am bashing FF and that's not my intent at all.
Best of luck
