I can honestly say that if it wasn't for Josh Scott that I probably wouldn't watch most of the epesodes, i'm not into flying planes so alot of it doesn't interest me, and even when I watch a show and he does something or says something goofy, I can show my friends who have no interest in RC flight and they have a good chuckle, he brings alot of entertainment with him to the show.
as for Josh Bixler, you do a great job too, the way you explain everything is very "user freindly" couldn't ask for better hosts IMO.
