I'm guessing there are a couple factories that make 90% of the arrows and various manufacturers order to their specs.
Technical clothing is made at the same factories. When I was visiting India I met someone who worked with one of these companies. He said they make north face jackets one day, patagonia the next. The difference is, for basically the same jacket, the north face would produce 900 a shift and patagonia 600, because patagonia had stricter quality controls and thus took longer to make...
That being said I have some Taipans and love them. I like being able to get collars, inserts, etc at a one stop shop.
