Well, I'm apologize if that offended you. I was just trying to answer your question and say that for the average you might not notice a difference, and that "you" was an indirect you. I wasn't trying to say YOU were a 'mere mortal'.

If you can feel the difference between standard plastic and graphite arms then congratulations because you are in the upper percentile of people that can.

In all the testing that I have done going back and forth between arms, I was not able to conclusively show with lap times that one was better than the other, and I would paypal some $10 if they could show me evidence with laptimes running back and forth throughout the course of a day that one was better than the other.
