moparman,

The Zebra strings can't even be compared to these top shelf strings.As far as stretch,there is none.Thats one of the strong selling points of the product,WCs' patented stretching process ensures the string does not stretch.As far as how long they last,...I was use to tearing up a Zebra at least once a year,mainly due to extreme serving wear on the cam end of the harness.Now on the WC stings they use BCYs' patented Halo serving which is garaunteed to never seperate,split,or break during the "usefull lfe of the product". So far I've fired thousands of arrows thru my Q2 and the string and harness still look brand new.These babies are AWESOME.
