For me I prefer a FF type string on my longbows,and I get my longbows just as quiet.A dacron string on some longbows can increase handshock on the bow.The bow feels more solid with a FF type string and not springy like with dacron.They are many different types of FF type strings like D97,8125,450+,Ultra Cam,TS1 Plus and etc.Some can sound louder then the next one,it's just finding the one that fits best.But a well made padded loop FF type string can be quieter then a dacron string.For me the only bows I shoot a dacron string on is a few older recurves I have,but rarely shoot them.JMO
