Anyone have any advice on where I can find feather fletched kids carbon arrows at a reasonable price?
I hope you don't mind some advice but for youth shooting I'd highly recommend one stick to Aluminum.
Carbons are great and I shoot them exclusively. However, I'm pretty involved in youth archery and carbon isn't worth the risk with kids.
About 3 years ago I was part of a testing crew for a carbon arrow that was billed as indestructible. We even approved it for a large youth archery program for 15 days during an eleven year period.
Then we broke one. We went back to aluminum immediately. Not long after one of our instructors was shooting this arrow at a cancer event and one broke and went through his hand.
