The difference is in materials as well as cost. (The ES being a little cheaper than the CS.)
We've noticed that because of the different material, the ES aren't quite as durable as the CS. But unless your planning on tossing the thing out your window on the way home, the ES would be just fine. Please no one try it, but I'm quite sure the near indestructable CS would survive getting pitched out a window at 75 mph just fine.[D]
Were you thinking a 6-1 or a 6-2?
