The first thing that noticeably jumps out to me is the tongue, but that's because I was given about 10 different options to choose from. Other than that, I'm not too sure what differences there are between mine and the retail version. I've got a friend that works at a LHS and is going to be heading to a massive demo day soon, so he's been tasked with finding out. I'd imagine there's a slight difference in weight too, based on previous pro vs retail offerings I've used. That's just pure speculation though.
