This is the waist belt I did with mine a few months ago. I stopped the sewing exactly when the Sit drag started separating from my hips, so I didn't get any added hip pinch.
The buckle was replaced with a cobra buckle with sewn stops on the tails. I tested falls on it, and even had it arrest a real fall when I had a climbing stick spin on me while climbing. It obviously isn't comfortable to fall, but I didn't even end up with bruising around my hips from the fall. I double checked the stitching after the real fall and not a stitch moved, so that is comforting.
