True. It would be ideal if he could find the Deadbolt 13 because you get a quality binding, but just cheaper and lighter. Good range too.
As for the Griffon I would personally stay away from it. It appears that you're still young so you want a binding that you can have for 3 or 4 seasons at least, and getting one in the 12/13 DIN range would allow some growth, but get one of higher quality.
