Schiz might know what I'm talking about but I don't expect anyone else to.
Scotty Kilmer on YouTube, the way his videos are comprised of clips makes me assume he either spends 90% of his day lecturing a camera with the same lecture in different places, clipping them apart and Frankensteining them together or he perhaps just stages incomplete portions throughout the day/week.
Either way, dude drops some knowledge bombs.
I get that feeling when watching his videos that things don't flow fluid like if you watched raw footage he may second guess things or feel like he's being too brash and talking down to people.
I feel odd taking his advice, I tend to go along with Eric The Car Guy or Jason Fenske that does Engineer Explained on just random car stuff.
