Shot Zebra string on two different bows. They do streatch, but are a pretty good string if you don't mind retuning alot. I just purchased a Berry String and cable and am waiting for them to arrive. I heard good things about Wayne Newberry's custom strings and they are about half the cost of Winners Choice. He makes them out of Ultracam in many different configurations. No streatch after they settle in(50 or so shots). Check his web site out. I believe it is berrystrings.com. Mr Newberry is also a pleasure to deal with on orders.
