Cougar your going to definately want to modify the seat somehow. As it is now it has really long straps that make the seat flop and twist around. Also theres no way to hold it back while your climbing so you have to rig something that will hold it back. I think they did an awesome job they might have just ran out of time making the new seat for this year. I wouldn't be suprised if they modified it for next year. Also how do you adjust the backpack straps while its on your back.
