Is there a difference in these bows between the 09 model and the 10 model? I saw an 09 hanging in a shop and it's spec sheet attached to it listed 32.5" ata and 7" brace which is different than pse's website for the 10 models. If they are different what and how are they different? Are both of these, the dreamseason and axe 7 considered 2 cam bows or are they a hybrid type?
