Why dont you get yourself a leather strap. They are very comfy, and will do NO damage to the kilt? Or sporran hangers might do the trick as well. I dont have any personal experience with them though. Great job on the conversion by the way. I agree that those stock things are pieces of junk. If you would like a leather sporran strap, but are worried about cost, PM me. I have a bunch of scrap leather and if I get your measures and time I would be glad to put together a black strap for ya!
