DIY horse bow thoughts and string

I recently built one of the DIY kits from Mead Longbows. This style of bow has interested me for a long time, but back when I was shooting often they were always expensive and I was more interested in learning to make bows. So when I saw Dave's DIY kit I knew I needed to make one. He does a great job with his video instructions, and it is a really unique bow. I love that he utilizes bamboo so well for the limbs, and having it be a folding takedown is nifty when packing for trips. The version I have is one of the original ones, which he has replaced with a newer geometry that is more efficient, as well as a longbow like version.

The part I have had trouble with is the Instant Bowstring string. It seems too thin for most commercial nocks, and the few bamboo arrows I have finished I just can't seem to get perfectly consistent. So I have three arrows that fit perfectly. The other thing is with the horse bow I found it a bit annoying to tie the big loop, and then have to use a bit to tie that a bit above the bamboo.
So today I decided to try a double loop string. I found directions here. I first made a flemish twist bowstring using 2 bundles of 6 strands each of B50 Dacron. The string I made was 40" with smaller than normal loops. I then used paracord to make the loops that attach the string to the siyahs. I really like this setup. It is very easy to adjust the string and get the right size loop. The next version I make will probably be a continuous loop string, and for that I think 40" would work. The flemish twist could probably be a bit shorter, maybe 39.75" or 39.5" and be a bit better. There is no reason that this could't work with the Instant Bowstring material either.

For that I would follow Dave's video instructions. And then one the brace height is determined, measure from the ends of the bits of bamboo, plus a touch. Then cut out two ~8" bits of paracord and follow the instructions linked above to make the loops. Then make a string with small loops out of instant bowstring. In this case you can even do an 8 on a bite instead of an overhand knot. The 8 is a much better load bearing knot, which I regularly trust my life to.
The only last bit of advice if you don't remove the core of the paracord it will be thick, and depending on the size of the nock in your siyah you could damage it. I ended up breaking the tip of my nock channel off because it was a tad thin. For my bot it is still seated well, and is really an aesthetic issue.
Now the next step is to start learning to shoot Mongolian style.
