Video of rope stress with a ropman 1 and kong duck

Good test. Thanks for sharing. Was I seeing right that the Ropeman and Kong Duck slipped slightly under the shock load? If that is the case it is possible that the slip might soften the blow of the drop somewhat.

Yes both the kong and ropeman slipped and caught again.

Great test, thanks for taking the time to film that and for sharing.

Conclusions will vary of course. As always risk aversion is a personal judgment, but it can and should be informed by objective information and collaborative discussion.

That prusik was impressive. Can't remember if I heard you say what brand it was. I just added the Aerohunter prussik/tender kits to both my tether and my adjustable bridge. I am impressed by how effective they are at 1-handed operation. Not as smooth as my Ropeman1 (which still lives on my LB), but close enough for me.

The Ropeman1 has received lots of praise on this site, and for good reason. It is an effective little piece of kit. I wonder if people had experienced the use of a prussik tender prior to hearing about the Ropeman whether they would have ever felt the need to switch.
 
Here’s a follow-up to this video from the NY Saddle Hunter guys. I believe this is directly in response to your post:

Doesn’t really seem like a safety feature to me, but I’m not the luckiest person in the world: I’d probably be the one guy whose tech would slip completely off.

Worth saving $ and my ropes even if I gain a few seconds of ascending time by using two hands or a d-loop tender. I don’t blame anyone for using the RM, almost bought it a few times myself for LB. I definitely won’t use on my tether though. Old school is my school on tether.
 
We've discussed this story many times at this point ... Don't have slack in your system with a rope grab. Friction hitches won't cut the rope. To each his/her own. Personally, I'm still going to use a rope grab for a LB. I think a rope grab is safer than a friction hitch on a LB.

If you are releasing your ropeman under a load you are doing it wrong. He should know that.

He says that it’s an abnormal way to do it, but he also says it’s not something a new saddle user might understand, especially if it’s someone who’s never been in a tree or used climbing gear before. Both the original post and this video address that.

The biggest scare I had as a new saddlehunter was grabbing my prussik to stand up. Glad I was only 3’ off the ground. Burnt my hand a little and it happened fast. That made me like the ropeman even more for new user friendliness. It actually requires a little effort to release a loaded ropeman. It should feel very wrong for someone with a little common sense. The takeaway is regardless of the components in your system you need to become familiar with them before climbing to height.

Right! This is why I said, "Personally, I'm still going to use a rope grab for a LB. I think a rope grab is safer than a friction hitch on a LB". Can you imagine doing that while leaning back on your LB. At least with a tether your friction hitch would hit the stopper knot and the tether is girth hitched to the tree. You're not hitting the deck, just changing your drawers.

Well i guess the olpux and kong duck did the best out of ascenders and rope it acts like a deceleration device like a rips stitch in a lanyard the way it skips through
 
Any guess how this shock load compares to a 2 foot drop of a 200 lbs human? Does the tractor in the video produce a lot more force? It is much heavier but probably moving slower than the person.

Edit: Turns out a 2 foot drop and you're going 7.7 miles per hour.
