Test pilots test the prototypes before the model goes into production, so that doesn't really apply here. And I doubt you really understand what fuzzy logic is, because you use it as a disparaging term, when in fact it is a very sound form of logic that applies to situations that may have multiple or partial results. My reasoning is solid.
I'm sorry you no longer like your LT, even though several months ago you were quite happy with it, and said everyone should buy one. I'm glad you like your Provari now. Maybe someday I'll buy a Provari, too. I hope that if I ever do buy a Provari I don't turn into a "provangelist" that hops from thread to thread praising people who buy Provaris and bashing people who buy Lavatubes. Yes, you do this, I read your post history. It's a big world with a lot of people, and each of them has different likes and dislikes. Each of us in this forum is at a different situation in our lives. What works for you may not be right for someone else. There's really no reason for you to mock anybody here.
Cheers!
