You are right about that ,but last year or year before<img src=icon_smile_blush.gif border=0 align=middle> I forget.I changed my string out with a Zebra,for a hog hunt in Florida(just because)and noticed the Zebra string stretching.I took an intererest in making my own and started using the 452.What is the qualities of the D75?I know the 452 is a low strech string and a bit slower than fastflight,and sume of the others.What is your take on this?Bill D&gt;
