Took my Maple/sinew bow out to shoot for the second time today & all is shooting well ,I made a continuous loop string with 2 7 strands out of B50 Dacron but was thinking of making a 2 9 strand string that would fit the arrow knock tighter so I don't have to put serving on the string,does ant body have any idea of how much speed I would lose adding 4 more strands ?
