For my dacron bows I use 14 strands up to 60#@28,you could go down to 12 strands B50 for the 46#.On my D97 bows 12 strands is strong enough for upto a 100# bow.I use 12 strand D97 on bows from 50# to 83#,it maybe alittle overkill for the 50# bow but it gives me the same nock fit for all my bows.I like to add 2 extra strands in the loop ends,It makes the loop ends a larger diameter and fills the string grooves better.And I feel it helps to make a quiter string by spreading the load out,just have always made my strings that way.I use .018 BCY No.62 serving for dacron.I like to use .024 Halo for 12 strands of D97,it gives me about .108-110 diameter and with 3D Super nocks,G-nocks and X-nocks with a .098 nock throat gives me a light snap but not to tight.
