picking a bow

[fordman]

I am 17 and 5 9' and 160 pounds, I work out periodically and am in good shape. I have been wanting to get a bow and was looking at the diamond rock, and the diamond razor edge and was wondering if the experienced archer thinks I could handle a 60lb draw weight and the rock. I really would prefer the rock, because I think the edge is used for kids. I am a first time bow hunter and was wondering if you people out there think the 60lb draw weight is enough for me to tackle? and would I be set not to upgrade if I liked bow hunting and got either the rock or razor?
