Granted, its mobility is freakin' impressive. 50ft. speed, brachiation, ridiculous Jumping AND woodland stride. It would be a very good skirmisher, but I wouldn't want it to stay in melee more than two rounds if I was controlling it. They've got a fantastic opening in a fight, but not much staying power.
Without Spring Attack, it's going to have to stay in melee. CR 8.
