So I just ordered 2 large x rings and I'm wanting to make a sling that has an x ring on both sides, one that I can take up with me and wrap it around the stem I will be using as a rigging point, my question is what rope should I make it out of? 3/4" tenex or stable braid? I will be putting a cordura sleev on it as well. Another question is how long s should I make it? Iknow I can use it in a basket configuration on horizontal crothes but what about using it in a false crotch configuration? I'm thinking of making it 6'... Any advice is greatly appreciated..
