That's an extremely competitive setup, especially for a 10 year old. I think he'd love it. You could get the Invert Too for $20 less and save a bit of cash.
Glad to hear that it's a good setup. His b-day is the 22nd of this month (big 11) and seeings how his mom won't let me buy him a new Mathew's bow as she don't want him out hunting with me yet (plus she was complaining about how much the bow was going to cost AND she thinks this is a good thing and cheap.... ) I'd figure I'd set him up with something decent.
