I need to buy a new bow for my 8 yr old. He has been successfully competing in a JOAD prgram for the last year and his skills have out grown his current bow which is a PSE Buckeye JR 54" 15lbs draw. I am going to get him a Hoyt Excel Riser in 21" for sure but my question comes about the limbs. I would like to get him the Hoyt Excel limbs but they are $200. I see that you can get KAP t-rex limbs for $90 or the KAP Winstorm for $120. Is there really any difference in these limbs vs. the Hoyts as far as quality/durabilty goes. They appear to be made from the same materials. I see myself having to up grade limbs again next year due to the inevitable growth spurts and strength gains that will happen.
