Every bow company borrows ideas from each other, some fail and some prosper. If all the companies that manufacture bows didn't "use" some ideas that other companies started, there would be many less bow companies to choose from. Personally I love laminated limbs over billet limbs IF they are manufactured right. From my perspective, any bow company selling bows in the $600 range on up should be ashamed if they don't use good laminated limbs on their bows. I best shut up now............I just bought a Bowtech.
