More sling questions

[Blake]

So if girth hitching slings is generally to be avoided, how do folks that use daisy chains attach them to their harnesses? I have always just girth hitched mine to the belay loop. Every daisy I have seen is wider webbing that the recent 8mm dyeema sling that cut itself.

 

 

Is there any chance of runners (skinny dyneema or others)cutting/failing if they are tripled-up and used alpine-draw style like a quickdraw?

The daisy chains are normally girth hitched to the harness. The difference is that they should never be subjected to a dynamic event.

(Here we go again on the physics stuff, but it is important to understand the difference between dynamic and static forces)

I don't think that really explains the failure from the other thread. He was rapelling. I don't think rapelling would generate significantly more force (although I see how it could)than using a daisy, especially for jugging.

 

What I gathered from the thread was that the severity of the bend contributed most toward the failure. It seems that the way a daisy is girthed through the harness doesn't yield the same sharpness of bend as skinny runner girthed to skinny runner.

I only use nylon daisies. I guess I would avoid using anything else. Although, the other materials, I guess mainly spectra, have been used so much that you would think we would know if there was a problem. I certainly would hope that we are not beta testing them! I have avoided using spectra daisies mainly because of not knowing when to retire them and the fact that the girth hitch is cinched and untied so often.
