Hello,
I tested the breaking strength of different modern material and FF+ came out close to 50 pounds.
It was not a 'scientific' test, I just tied the string samples around a bucket grip (soft and smooth and without a knot) and filled in weight until the string broke.
I repeated this procedure more than a dozen times with each string material I tested and avaraged out the results.
That's also the way I test linen and other natural fibers and it worked well so far.
By the way, Dacron B50 and B500 registered at about 35 pounds, D-75 at 65 and 'D-75 thin' at about 50.
ciao,
gian-luca

Thanks for all the input guys :).
I went with 14 with a couple of extra strands laid in at the loops.

Excellent. Thanks for sharing.

Those breaking strains concure with my testing as well.
A really good linen string is the same or not much bigger diameter than b50 of evivalent strength in my experience. Bickerstaffe has jumped to conclusions about nock sizes and that sort of thing IMO. Those strings would have been made from the finest materials available with superb knowledge to back up the process.
Using fastflight I would use 8 strands with a dyneema serving for performance . 12 for all 'roundedness' and 18 for a 'last for ever' string.
