I favor GCN. I do a little Vegan Cyclist videos as he's down to earth.
Have to admit I was half thinking of doing an Everesting before I saw the episode where Vegan Cyclist failed. I was like, crap, if that dude couldn't do it ain't no way I could give it a shot.
I do Gaimon once in a while, but I think with the recent crash it's about time he needs to figure out how to make a living outside of bikes and move on. His voice and delivery isn't very good in the videos versus his writing in books.
