Nice to see you found out about it from the horses mouth. Don't know ho much you know about these older bows. It's probably still a shooter, but if you should ever have to change the string do not use a fastflight material. Use Dacron or B50. The limbs are not designed to handle the extra stress involved with no-stretch strings.
The lady I spoke with on the phone told me the same thing about not using fastflight strings. I'll stick with conventional strings.
