ChuckC, back in 1997, Mr. Bob Lee told me face to face that FF would destroy his bows, and probably anybody else's. He made no bones about it, so I've kept my wife's and my bows from that era strung with Dacron. I know that now Mr. Lee uses FF, and I know that lots of people use modern strings on vintage bows. I would be a basket case with worry, so there's no way it would be worth it for me to try. We live in a wonderful free country, and people can make decisions for themselves, just as I've done.
