I'm not sure if I am the other one, but I mentioned it briefly in my trip report on the Yampa River. Mine was a full length webbing strap from the manufacturer. It is almost two years old and I had not inspected it recently and I was at a maximum span. I was trying to maintain the proper angle, even climbing up the tree a bit to raise the attachment point. It was dark when I climbed in and it possibly was wedged improperly in the buckle. It tore completely through in a long ripping sound, which was heard by others nearby. Fortunately I had a soft landing on a mulch covered ground.
It would be helpful if the vendor that sold these straps would step up, take ownership of the problem, and join the discussion. Serious business, this.
Also, we need to explore the role, if there is one, of Dutch Clips in webbing failures. DCs were in use in this case.
It's generally agreed that Dynaglide whoopies are pushing the lower limits, strength wise, for suspensions. That being the case, 700# straps seem destined for problems.
It has always been my private conviction that any man who pits his intelligence against a fish and loses has it coming.
i am not even sure if i care about the load rating. Polypro is just not safe in my opinion(obviously 2000#+ will be pretty tough, but heavy). It is much more likely to let go at any spot of abrasion. I tested some for a few weeks and the webbing broke inside the marlin spike hitch. it looked like the friction melted the webbing to the point of failure. I think my whoopie may have slid behind the knot instead of resting on top of it but still i need a higher safety margin than that.
That aside, I was looking at strap works's website and came across this sentence. "Polypropylene does not have a high abrasion resistance." So Its possible that I rubbed a worn spot into the strap because I hang from the same trees often and thus the same spot rubbed every time.

If you don't try due to fear of failure you've already failed due to fear.
good reason to avoid polypro for tree straps!!!!
Not saying polyester is better, just saying suspensions need to be checked often. The more use, the more frequently they should be inspected; regardless of the materials used.
