Say, I need to make adjustable slings, your slider and belt loop kind of strap. I've some 9 oz English bridle, but I'm wondering if it's too thick and firm for this purpose.
I've also some 7 oz latigo that feels less rigid, but I wonder if it's good to support a load of ~8-10 lbs. I could line it with suede, but I'd rather not stitch 100 inches of strap.
I know that for slings one would want leather that won't stretch, but I'm thinking I also want it quite pliable. What's the best temper then? Is firm too rigid? On a firmness scale of 1 to 10, down to which number is acceptable?
TIA for any helpful input.
