Webbing or amsteel?

You can see in this photo what I did. Basically I ran through dano’s triglide as usual making a loop for the carabiner then ran my tail end over and back through a third time to lock it essentially. I like being able to remove my bridge and once I find the length I like I will probly remove the triglide and tie it in at length

Why do you use a caribiner on one side? Couldnt 2 triglides be used with no caribiner? I am looking at trying the webbing and triglides since I just have the fixed 30 inch bride on my mantis.

Doesnt the photo of the 'beener in his link show 20KN?

I was referring to the stamp on the roller part of the carabiner in the photo, the only visible stamp being WLL 4 KN. I was asking because I have been told as a rule of thumb to keep everything rated at or near 20KN due to the potential to shock load with minimal slack in the system which can generate ~3oooish lbs of force and cause failure to the weakest link.

the WLL is the same as SWL, so 900lbs is quite strong, the major axis strength that most people focus on is 20kN or 4496lbs...

I was merely pointing it out incase you had not taken it into account. That rating is confusing being it is so low compared to the major axis rating. Not trying to be the saddle hunter safety police but don't want to see anybody get hurt either.
 
If you ever fall the webbing will serve you better, bit of stretch to make the fall more dynamic. Amsteel doesn’t do well with shock loading, and it will not stretch at all.

Not the only reason I prefer webbing but it’s another one to consider.

the carabiner is so I can just unclip the bridge. I then run it back and forth through the bridge loops and clip it back to the loop essentially like shoe laces if you will. This forces the bridge loops and bridge to stay tight to my body and streamlined to help avoid snagging in brush during the walk. I find I like it enough I may remove a sys hauler and just utilize one rather than 2.

No offense taken here, but I think you are confusing MBS with WLL or SWL. The MBS for the tubular webbing you are using with one water knot is about 4340lbs or 19.31kN. So a typical 5:1 WLL/SWL on 4340lbs will be 868lbs (32lbs less than the Petzl Z). Add more knots and friction gear to your webbing and that number decreases. Your carabiner also has a WLL, which is probably a factor of 1/4th or 1/5th of its MBS too. The manufacturer specs should state what their WLL rating is. Its important to understand what all these numbers and ratings mean.
 
You’re right for listening to the OG’s in this thread. Webbing is king in my book. And it’s gotta be the soft stuff. I would say it’s the most “predictable” when you want to shift.

Thanks that’s why I was asking. Typically on the carabiners I have it shows 25kn major and I think 7 on the minor or against the gate. It doesn’t have a stamp on it for WLL or SWL that’s where the confusion came in I believe.
 
I’ve never used webbing for a bridge, but I can imagine it works perfect. Don’t have to worry about strength, it’s more than strong enough. I like the Amstel though, it’s even stronger and lighter weight and more compact. It’s less abrasion resistant, but that has not been a problem so far.
