Mine came with the bow. It was on my Guardian and all I had was trouble with it. I switched it out for a factory string and after 100 sticks it was settled again.
I haven't had enough experience with them to trash them entirely, but I can speak positivley of my World's Best. I kept getting the same answer (from different people
) when I asked which string to go with, so I went World's Best. Couldn't be happier.
JB, I wouldn't blame you, if one doesn't work and the other does for me consistently I would be all over it. I wasn't challenging yuor comment at all, it's funny how the same products can pop lemons on us.
All I can say is the WC string didn't agree with me (just once) and the Scorpion strings, where to be frank, are junk. I really like my World's Best. I am at about 200 arrows throught the fresh one and no perceivable stretch yet. It is eerie.
