2011 vs 2012 Murray boots

Can anyone tell me what the difference between the 2011 and 2012 Hyperlite Murray boots is? From appearance, it just looks like thy changed the exterior texture a little and made thm all black. I was wondering if there were any other differences. I kind of like the appearance of the 2011's a little better. I was thinking that I might ask for the 2012 system bindings and the 2011 boots if there is not much difference in the 2011 and 2012 boots. Also, how do you go about heat molding them? One thing that I have noticed about Hyperlite is the informational materials that come with their equipment is not very informative.
