Well, I guess I guess I,m the black duck, I don’t mean to be controversial but... In 1972 I bought my first real bow yep a brand new browning cobra ,paid 140.00 for her loved that bow.since then how many bows I’ve owned and shot Ihave no idea ,hundreds. About 12 years ago I was really unhappy with the strings I was using ,basically B50 and B55 and discovered SBD strings, everything improved,speed ,noise ,vibration and no streach. My next SBD will be my 76th string,how I kept track I don’t know.Anyways that Cobra has 3 laminations of glass on the tips ,basically bombproof.Pierre makes his skinny FF strings with B50 tied into the loops..I’m down to about 40 bows ,of every type made ,custom recurves and longbows ,Asl’s Elb’s, China bows etc.etc. They all wear SBD strings and I’ve never had a problem ,just a lot of enjoyable shooting and they wear like iron.
