Yeah, I can see him as a P-lead. Here is a nice quality video of him - eyes and hands.
Here is more like the video you posted. It's like two different people. lol.
My first guess would be NeTi... but I am going back to look more deeply into the difference between Fi and Fe. His smile reminds me of the NeTi's in the Larin videos - but his never seems to go away!
Remember when I said it looked like he had an Fe smile, but the smile never seems to go away? Take a look at Richard Feynman who is in the official TeNi video. Check out his mouth (it will look familiar):
If Feynman uses TeFi, then Jamie Hewlett might also use TeFi. They both have that constant smile as they talk.
