I'm not going to put any holes in it. The strap button is on the back so no way to extend that with a single fixing, it will just rotate. A wide strap pulls on my damaged shoulder.
I was at sw bash 2 years ago with a waist strap made from a weightlifting belt, but it needs holes drilling.
It's an absolute beauty to look at and to play, if I end up having to move it on I can't be putting holes in it.
