I saw a commercial for it and set my DVR up to record the series a few days ago. I hope it is worth watching.
Although I am not that well rounded, I seriously considered trying out for the show when it was announced last year that they were looking. I know and have shot against Blake, Mike, and Simon (he goes by "J.J." and has been nicknamed "the Razer") at USPSA matches, and there are a couple other USPSA/IPSC shooters that I don't know on there (Adam, Denny, Brad) and Caleb shoots Steel and IDPA.
It will likely depend on the match ups and the particular disciplines involved from week to week as to who does well and who goes home, but I would be hard pressed to bet against the top USPSA guys. There was also an experienced 3-gunner (I forgot which one) that would probably be a decent bet.
Looking forward to the first episode. Just hope it is good!
