I recently put a new buss cable on my Legacy due to serving wear near the cam. The new cable doesn' t have any twists in it. Is this a problem? Also, I re-served my center serve on my bowstring and didn' t pay any attention to the direction of my serve. Does it matter if you serve with or against the twist in you string? I guess I should replace the string at the same time as the cable but the string is still in decent shape. Also, my bow shop sells Zebra strings and I' m wondering if I should step up to Winners Choice strings and cables. What do you think?
