I need some help trying to figure something out. I have a string that needs replacement on a longbow I have. I have the old string. I am going to make a new one, but I'm not sure if this old one is Fast Flight or Dacron or whatever. I'm afraid to make one out of 452 and use it when it might take my bow limb tips apart. How can a guy identify what the old material is that came on the bow. All this string material looks pretty much the same to me. My longbow was made a about 10 years ago by Bob Lawson. It's a great bow. I won the bow in a drawing and he donated it to the club holding the tournament. I would prefer to use a newer kind of string material, but if I have to use B-500 I will. I sure would hate to ruin it. Thanks, Gapmaster
