It's not really a case of "whatever's legal", it's just that there are so many options available now. Carbon arrows were a rarity 15 yars ago, aluminum was king. We now have carbon in bows, foam limbs, superior glues, several bow string materials, many takedown systems. Before about 1950, there was no fiberglass used in bows, they were all wood or backed with any of several materials. String materials have gone from flax/linen to dacron, to FF. A lot of primitive shoots have "no fiberglass, no aluminum, no plastic nocks, no synthetic strings"-is this where we need to go, limiting what's acceptable? What's allowed in competition is one thing, but for personal pleasure or hunting, who gets to decide what is and isn't acceptable as "traditional"-the wood bow shooters, the 50's/60's Bear shooters, the ILF folks, the 2 piece shooters, the 1 piece shooters? When we start declaring what is or isn't acceptable, doesn't it then become who's right and who's wrong?
