It has the potential to use the true FULL length of the bow
Leaving the string always knotted is also another benefit
I wonder if stronger tips are needed

Yes you definitely need to wrap sinew just below the tip so it doesn't split the bow upon the release of an arrow. I had that happen on one of my tests but the sinew holds it together great!

Really interesting.
By the way beautiful full draw

I love it when I check in for the heck of it just to skim the forums and stumble into a gem like this thread. Looking forward to doing this soon. Thanks.

Hey thanks everyone!! And let me know what you guys find out in your own tests. The more data the better!! Also I found you can make the tips thinner too.. reducing limb weight even more. The tips only have to really be about a couple millimeters wider than the string. Then you can put rather small string groves down to hold the loop. As the string wraps from the back to the front it has some mechanical advantage and does not need as much to hold it down.
One could probably get the limb tips 1/4" to 5/16" thick, depending on your strings thickness.. if you were trying to push the performance even more that is. I don't know how historically accurate that would necessarily be.. but it would work.
GlisGlis:
one thing that puzzles me is the pronounced V notch shape of the pajute bow fragments
It seems to me that a U shape would be more appropriate and would reduce the risk of the tip splitting
