Maybe, I have an old Martin semi-recurve that started to delaminate near the tip after fast flite usage, I stopped using the bow. of the 150 bows in my collection, I shoot quite a few and now I never use anything but Dacron.
I agree with zep, not worth the risk.
There is no real reason, imho, to use a non-dacron string. If you are trying to get increased speed, just get a modern bow which will gain you more. Dacron strings are readily available today.
