David, I'll be happy to make and send you a string with one loop and a bowyers knot on the other end. You can use it on different length bows by moving the bowyers knot. That's how I make all my strings. Send me a PM with a mailing address and I'll have it out to you soon. I have red, black, yellow, white and green B-50 string material so you can even choose colors.
Your limbs are bending nicely but not together. You are over stressing the right limb and it may take more set because of it. Pat
