Speedmaster connecting rods

From what I was told some rods. Scat , eagle , Speed master , ext. are all the same just a different name . That is a great deal for those rods . .

High dollar rods just go through a better quality control system. You pay them extra to xray and blueprint to make sure they are perfect. They may find 1 out of 1000. Your paying for confidence in your purchase. And in today's world whats it worth. What do they actually do with that one bad find?
