With all the attention to detail on primitive bows I would have
thought a lot more people were using natural fibers.
I seem to going backwards. I shoot a 74 lb @ 31" laminated long
bow. I've managed to get a pyro supplies 70 lb 8 strand linen
string with two flemish loops to hold together for over 300 shots.
I've broken at least 6, six strand linen strings very quickly.
Two broke just standing with the strung bow against the wall.
I've been serving the linen strings with a light hemp thread.
My ultimate goal would be to make a nettle string for that same bow.
The 70 lb imported linen from Pyro Supplies at 8 strands is just
standard nock width without serving. I put on a thin hemp serving
and it seems to squish down in the nocks. cheers fiddler49

I made my first string from B-50 last night. I was unimpressed. I'd rather make two linen than just one B-50.
I like simplicity, so I use 14 stds of Dynaflight D-97 on all my 45 - 70# bows. It makes a nice diameter string that only needs one wrapping of serving (which tends not to work loose like double and triple serving wraps needed on thin strings). I like D-97 over B-50 and fastflight because there's virtually no string stretching, which means there's no fidgeting with brace height over time. I also think it's quieter, and as a bonus it's faster. In the lineup of the latest string materials (D-97, 450, etc..), D-97 is also near the lowest in cost.
I admit I like the concept of using natural linen strings, but in practice every one I've one I've made has broken sooner or later. (Some much sooner.) I don't like having to worry and wonder if my strings are near the end of their lives and have to perpetually replace them on all my bows. I've never had to replace a D-97 string.

Adam, sounds like your string choice is virtually identical to mine (for my modern bows), only using BCY's dyneema where I use Brownell's dyneema.
FWIW, I have found dyneema to be as much superior to fast flight as fast flight is to dacron... And I have found it to make some of my worst modern bows actually behave as if they were half way decent.
As far as durability, sometimes its tendency to "fuzz" up worries me; but I just wax it down, and replace it when the fuzz starts balling up. I have gotten a year of hard shooting out of these strings, and only replaced them as a precaution. So far, my strings have been pretty much bullet proof. Not broadhead proof, though... And on that occasion I only cut through half the strands, and the string held until I could unbrace the bow and replace the cut string with the spare I habitually keep taped to my riser.

Im using D-75 thin too, 20 strands. I have to add 5 pieces of strand under the serving to fit the nocks.
I have made only one hemph string, it felt like D-75 before it broke. Have to try again someday.
I dont like it how B-50 streches but Im using it for tillering strings.

I was wondering how you figure out loop 2 loop when making your dacron string for a new bow. The bow I finished is 68 n2n would like to have 5 1/2 BH plus how do you make up 4 string strech . I have b-50 from brownell.
