For the first time, I tried a D Loop on my compound and love the way the arrow nock is positioned being pulled equally from top and bottom. My only question is the safety of the D Loop knots itself, even with melting the string ends into a mushroom head, I get kind of a uneasy feeling. Have these knots ever failed? and, is there a safer way of tying these knots? I saw somewhere a person mentioned a "clove hitch" is safer.
I guess you can wrap a few turns of serving directly behind the mushroom head as extra security.
