For some bows, inversely, those characteristics are lethal. For example, I own a horn composite bow (thanks scars!) and per all builders, but quoting Adam Karpowicz in his book "Ottoman Turkish Bows, manufacture and design
" using FF strings destroys both the nock ends as well as can cause delamination. He tried every permutation, only to end up losing bows, no matter if they were reinforced with rawhide, sinew, horn, or whatever. While many who have contributed know about this property, I'm sure someone will have need of it.
I wish I could use FF materials, but my nocks are tiny and would be cut through almost immediately. B50 or silk are my only good choices.
