I must say that I find your coughing surprising. I have a sensitive throat / lungs myself and I have only coughed at the times when I took WAY too big of a hit.
I definitely agree that you can taste the SS. I don't find it to be a deterrent, but it definitely doesn't taste as good as the Ascent or Solo.
The coughing issue is surprising to me as well. I will continue to play around and see if I can figure out how to hit the FF without cracking a rib. I find the taste of the vapor to be very good, but that SS taste is detectable.
Interesting. I find it super smooth. Yesterday I was playing with the MFLB for the first time in ages. Got huge hits from it, but very harsh. The contrast with the big FF hits, which sometimes make me cough but never leave me with a harsh feeling, was quite pronounced.
Not really sure why you are having issues with harshness. Sounds like you've been using it long enough to be high on the curve. (I do agree with the "current heat state" observation..a cold FF requires more heat button action, and as it warms up, pulling big hits becomes faster and easier. Till the material starts to get spent, that is.)
The odd thing is that I don't really find the vapor to be overly harsh at all. But I get a reaction in my chest a few seconds after the hit. Go figure.
The LB is by far the most cough-inducing vaporizer that I own. I still love it, but hardly use it anymore after it (literally) sent me to the chiropractor.
