RE: Too young for a " real" bow?
I' m a PSE guy but for this I' d have to say look at the Bear Badge. My son is going to be 10 in January, and we set him up with a new bow two months ago. I was looking at the Spyders and nothing would work like you wanted, if he could pull it back, the max poundage would be too light to hunt with. I didn' t want to sink $200+ for a bare bow he' d never be able to hunt with.
We went to a pro shop and found the Badge, they took it clear down to about 22 lbs to start him out with. The description says that they the adjustment isn' t that big, but I' d check with your pro shop. They said that it was much more adjustable than the others.
