I prefer D97 for my favorite string material,I make a 12 strand with 2-3 extra strands in the loop ends with .024 Halo serving.A 12 strand D97 is strong enough for up to a 100# bow.I have the same strand count on bows from 50# to 83#,it is more then I need on the 50# bow but it gives me the same nock fit on all my bows.I feel the extra strands in the loop ends helps to quieten the bow also because it is a larger diameter,it fills most nock grooves good.And you can get D97 in more sizes,you can get 375 ft. rolls and 1/8# and 1/4# spools.And I find a 1/4# spool cost less then most of the other strings,just alittle.It is a tough and long lasting string in my opinion.
