I just have seen no reason to get one. I don't spend my time trying to discredit you, or trying to look smart. I simply argue to get to a point. I, and many others on this forum, would like to see claims backed by proof. I do this same thing for the endless argument over exhaust design, or any other mod. Don't be so full of yourself and think that somehow this is about you... it's not... it's about your product, mores pecifically how it compares to JWT.
