Rope questions?

I have rope questions…

I was looking into getting thinner ropes to pull. I’ve always been told to use static ropes for rigging. But after reading the difference between low stretch and static rope. I’m not sure the is much difference. Static rope (less then 6% stretch) might be better for actual pulling, but low stretch (6-10% stretch) absorbs impacts better. Thoughts?

Part two: if I’m also making rope belts… how thick should the rope be…. and also static or low stretch
