For the Xtreme being close to the attitude shift, you may find you will need a surface change for the attitude shift. I still have my Xtreme and just got an attitude shift and it is outhooking my xtreme by at least 8 boards with similar layouts and both left at oob finish.
For those of you who will say that comparing a new ball to one that has "x" number of games on it isn't fair, I take good care of my equipment and I haven't seen a decrease in reaction for my xtreme.
All of that being said, I love my attitude shift because i am in a part of the lane a lot earlier than I am accustomed to, and I am able to play inside of most everyone else.
