I never found a 30' strap exactly like i want. I am still going to get one.
I am revisiting the rope idea too.
I was going to order this one but it is out of stock. 11,800 break strength
Bailey's - 9/16" BlackMAX DB Yellow Bull Rope
My second choice was this one. 10,400 break strength
Bailey's - 1/2" Samson Stable Braid Blue Bull Rope
Then I got to thinking about amsteel blue again:confused2: I know with a rope if you tie a know it can reduce its strength between 20 and 40 percent. Splicing it doesn't hurt it in most cases. The amsteel blue has a thimble on it or one on each end. So if I went with the 3/16 amsteel to stay on my budget

How could I attach it to the tree with out reducing its strength? Then it would be about as strong as the other ropes I mentioned with a knot in them. If I got one with a hook and pulled the rope through the hook would it greatly reduce the strength? My other idea is a short tow strap and hook the amsteel to that. Any other ideas?
