If you still have some of the older, made in USA, Spitfires, they're probably great. The newer Chinese ones are made with lower grade Chinese steel. They're probably still OK for turkeys, varmints, but I wouldn't trust them for big game hunting. There are so many excellent USA made broadheads, why risk your hunt on Chinese steel. My Asian mechanic says: "Even steel made in Thailand (his homeland) is better than Chinese steel." He won't install any parts made in China, on any vehicles he works on.
