Any body ever had strings that fray from touching (slapping) the limb ? I just got a new bow shooting and was starting with low brace heights & frayed the 10 strand FF plus tiller string it frayed not at the knocks but about 4" down from them so I remade a 12 strand string & ended up the same issue , there is nothing sharp or ruff or any thing like that I have had other bows that slapped the limbs but never frayed ? I will start higher next but just thought it was strange ?
