If a Turkish Double Loop is added to both ends of bowstring, how much will it add to your draw length?
A what? :saywhat:
Killdeer :dunno:
Exactly the same as putting on American double nocking points? :coffee:
It won't add anything to the draw length. How could it? It's essentially nothing more than replacable loops for the bowstring.
I don't see any advantage to using it with today's bowstring materials. If your loops are worn there is either something wrong with the nocks - if they are worn prematurely - or the string simply needs to be replaced.
