Alternative to the traditional alpine quickdraw sling

For my alpine draws I currently use regular Dyneema slings.

I have encountered three inconveniences from using such slings.

Firstly, the stitching where the ends of the sling are joined is free to move around and often creates a problem when extening the draw as it can jam at one of the carabiners, preventing further extension.

Secondly, for safety reasons I believe it unwise to use a carabiner retainer (eg. Petzl String) due to the possibility of having the carabiner attached solely by the retainer, resulting in a quickdraw that will come apart at a slight tug. See the video below.

Lastly, the sling is prone to locking up on itself when one is trying to extend the quickdraw, I believe the cause of this is the friction generated by multiple sections of the sling being slid over one another.

I see a simple remedy for these issues to be using something similar to a web-o-lette (a single length of webbing with two loops sewn into the ends). See here for a more detailed explanation.

The use of such a setup would eliminate the possibility of the stitching getting caught whilst sliding through a carabiner as both areas of stitching would, at all times, remain just below their respective carabiner.

Additionally, the loops would mean the quickdraw would be unable to be in a configuration where one carabiner was supported only be a carabiner retainer and not the sling.

I also believe it possible that the setup would be less prone to jamming up on itself as at each carabiner there would only be one stand of webbing moving over each carabiner, rather than three.

The system would also use less material, saving (albeit very little) weight. It is possible that this weight loss would be negated by the additional stitching.

Alternatively, a sling could be sewn into a shape resembling a figure 8, with one loop just big enough to fit a carabiner.

My question is, why does no such products exist? (That is, if none do exist)

I believe simply sewing the two strands that are in between the carabiners together might be a DIY solution (note: the stitching would not be required to withstand any force to maintain the integrity of the quickdraw).

However, such a process is not particulary appealing to me due to its time-consuming and messy nature and also the fact that it carries the possibility of comprimising the strength of the sling. I can imagine it might also make extending the draw harder.

Any comments on the subject would be appreciated.

Thanks in advance

Are you talking about a Rabbit Runner ?

Thanks for the replies guys, I never knew they already existed!

I just realised that I can simply tie a slip knot around the lower carabiner, next to the stitching. Problem solved.

Can't decide if this thread is serious.

If it is - tying a knot will reduce the strength of the sling. Don't do it.

Either learn to use doubled/tripled etc draws properly, or buy some rabbit runners.

Safety is primarily situational awareness and proper gear use. Not creating contrived ways of avoiding perceived risk.
