I can build you a Improved soft shackle if you wish in Black AMSTEEL 5mm
AMSTEEL-BLUE - Samson Rope
AmSteel-Blue is a high-performance 12-strand single braid of 100% Dyneema ® fiber, AmSteel-Blue yields the maximum strength-to-weight ratio, very low stretch, and is stronger than the same sized wire rope—but it's so light, it floats. It has extremely low stretch, superior flex fatigue, and wear resistance
I'd say the working load starts around 700lb with these
Or Red UMPE 12 Strand
Ultra High Molecular Weight Poly Ethelene Similar unbranded
I'd say the working load on these is around 700lbs
I typically make these from 5 ft of rope, as it's a good size, I try to optimize the size on these.
If you want a tradional style I can make you one with a small pick line as I love that style.
