Bonfire blur,…

So I think I finally settled on a jacket, but Id like to know if anyone has used the blur before? Also, this is a bit of a long shot but I am wondering if anyone has used or at least seen the 2011 or 2012 models, I found a few online for a lot cheaper than the 2013 but I would like to know what has changed before buying. Unless anyone knows where I can go to find that info
