What happened to the guy with “failed” oplux?

I say knot failure as the sheath or covering makes it harder to hold a knot. I feel anyway. I actually wrap tag end of knot tight with electrical tape to help. Shawn
 
I have rappelled on wet Oplux many times. It’s not ideal, but I’ve never felt that it was dangerous. I switched to the Rescue Tech mid season and can’t remember a time where it got really wet to try it out.
FWIW, I actually prefer the Safeguard/Oplux-Rescue Tech over the Canyon C IV. In other words, if the Canyon was just as light and had the same bulk as the 8mm stuff, I would still choose the 8mm for ease of ride down.

I also prefer the 8mm because it packs so nice but it is a jumpy ride down when wet. If the rescue tech doesn’t absorb water as bad I might consider switching to that. The canyon rope just doesn’t pack into a pouch as nicely.

If your using a sewn eye oplux tether, sewn auto block and tie a figure 8 on the end of the rope to clip back in your carabiner, your chances of failure are very minimal. Like hitting the powerball odds...

The rope sewing group that many use (name escapes me, you can send your stuff to them to have it sewed) report that they have not had a single failure of one of their products ever in the history of their company.

If you tie your knots correctly your chances of failure are very minimal...

I have some stuff sewn by Iron Street, I think they are part of Wespar Tree.
 
It’s not the leaning. It’s having a fall of 4 feet on a 2 ft rope, work out of spec gear. It’s the kn generated from such a short static fall that these static ropes just aren’t built for.

I disagree. The rope is built for it, your body is not.

If your rope has a MBS of say 5000 lbs and you tie a knot that decreases the MBS by 50% well your rope is now rated at 2500lbs

Here is the thing....If you experience a fall that generated 2500 lb /ft of force....you aren’t walking away. Your guts turned to jelly and your hips and back are broken.

Knots decrease the strength of the rope by anywhere from 25 - 50 % depending on what knot, wet/dry, how you dress the knot. This has been tested, but most professional engineering firms will tell you it’s not exact because of the multiple different variables within each knot. This is why most ropes the “pros” use are 10-11mm with around 10000lb MBS.

I think the ones I am referring to are Rope Logic. I do have Iron Street stuff too. Excellent work. Check out Rope Logic's website, cool stuff. They seem extremely legit and serious.
 
He hooked the Oplux to a static object (the front of a tractor, if I'm not mistaken...), and then introduced about 5' of slack into the rope before throwing it in reverse (it was a UTV, not an SUV as I stated) and slamming against the rope with both mechanical ascenders in play on back-to-back "pulls" ... Scientific and worthy of TMA testing, maybe it wasn't -- but it did show me and others the tremendous amount of force that rope would take, even with a device biting into its sheath at extreme forces. That rope ain't breaking just with someone leaning against it tethered into a tree. ;)

I think that's a cool experiment. The way I first read it, I thought he tied one end to an SUV, one end to a saddle, and then took off sprinting! I was like "you didn't try to stop him and was cheering him on!"

I did a similar experiment where I girth hitched on 1/8" amsteel daisy chain to a tree and another to my tow hitch and then tied the two daisy chains together with a simple knot. It broke so easy and melted the knot. When I joined the two chains with a soft shackle, it held fine. So I learned that knots really do decrease amsteel strength a lot.

I have heard of them, I’ll check it out
 
I've used Oplux for two seasons and 1 stick/rappelled half of this season with it. Never had an issue. I did notice when rappelling with the lifeguard the sheath would shift downward towards the bottom a little. But no problems overall. I don't really see it just breaking. It's crazy strong. Ever try to cut it? The core is pretty tough.
