My boys (9 and 11) are shooting a Diamond Infinite Edge (40 lbs) and a Bear Cruzer (50 lbs), and I've set them up with my old Beman ICS 500 arrows, which I had plenty of after I switched to 340's. Aluminum arrows bend way too easily, and the fiberglass arrows you can get cheap(ish) seem simultaneously dangerous and worthless. And I've just gotten to used to griping at them when they break or lose too many, and then go buy some more.
One thing - I've found that judo points are worthless for squirrels. We've shot at least three with judo points, including one from my Hoyt, and had 'em run off, sometimes with the arrow still sticking in 'em. Use a point that'll get all the way through. Might be different with rabbits, of course - they don't seem quite as tough.
