I am not a fan of B50 or B55,the only bows I have dacron on are a couple of older vintage recurves and I prefer to spin up and endless loop string for them.Everything else I use some form of a low stretch material.Just don't care for the feel of dacron.I have been making my own strings for as long as I've been shooting traditional for around 20 years.First thing I learned to do was to twist up my own strings.I use D97,8125,8190,450+,Angel Majesty and Ultra Cam and have no problem making them quiet.I don't shoot a FF type string for any performance increase.For me the bow just feels more solid and not springy.
