I'm not a bow hunter, and am not really archery-savvy; any opinions on what a good starter compound bow would be for kids? Was looking at a couple online, but as usual, the reviews on them show some stellar reviews and at least one guy that thinks they're crap. It's for an 8 year old - but be aware that he is a big 8 year old, so he could probalby handle something a little more stout. Any advice?
