Agreed. Cody is a burly SOB - seems like the nicest guy in the world, but I doubt many internet tough guys would be so quick to call him a moron if they weren't hiding behind their keyboards.
After watching a few episodes, I tend to find myself siding with Cody's careful, methodical approach, over Dave's more flashy, risk taking outlook. I'm sure that is a deliberate difference being created for the sake of making the show dramatic, but the presentation of two very different approaches is really enjoyable to me. I don't expect anything other than some entertaining TV, with a little bit of knowledge being passed along during the way, and I end up really getting a kick out of the show, even when it's obvious that stuff is being played up for the cameras, for the sake of the Discovery producers.
