15 strands of D97 with .025 serving holds onto Bohning Classic nocks just fine for me.
Bowjunkie, D97 changes the feel of shooting a wooden bow in a very noticeable and desirable way. probably shoots a faster arrow, too, but you'll need a chronograph to prove it. I don't understand why anyone would keep using B-50 on their wooden bows if they can get Dynaflight. is no comparison, imo. and it is absolutely a myth that dynema fiber strings will do harm to wooden bows.
