Hi
A couple of years ago my then 6 and 9 year old sons wanted to start shooting " real" bows with their father and I we got both of them the PSE Spyder. If the Genesis bow had been available then we probrably would have started with it.There is a lot more adjustments with it.The web address for it is
www.genesisbows.com The boys like their PSE but it cost us over $400 to get each one set up and my now 11 year old is too big for his PSE.
I do agree that going to a good pro shop in your area is the best place to start.
