The idea about the belt makes perfect sense, supporting the weight of the horn around your hips rather than upper back. So I got the idea to use the hook mechanism off the MW Harness and attach to a weight belt. It worked beautifully! I am extremely happy with this setup, and it is extremely sturdy. The belt was $30 and screws/nuts etc. came to $3.98. I now need a ring solderd to my Eb and we're good to go!
As you can see I used 3 pieces from the hardware store. The screw, the locking nut, and sleeve like piece to keep the leather holes from stretching out. I didn't have to modify anything, the screws/sleeve fit right into the holes in the belt.
