Please tell me what I am missing.

I use them. Rephrase...I have them amongst my recovery gear and seldom use them. I only use them as a Plan B in instances when a normal shackle is impractical or unsafe.

I also have a set, lighter and easier to pack away..... supposedly as strong as the old metal ones

Sure, but what earthly reason could there be for attaching a soft shackle to a metal D-shackle as shown in the video link?

The ONLY benefit, when using them this way, is that the Bow-Shackle doesnt need to be undone. That is it.

i think the actual point on the car is sized for the pin on the bow shackle, the soft one probably wouldn't fit
and if it did, unless the edges of the point are rounded, that 90° steel would cut that soft shackle quickly (minimum radius of the rope)

from what i've seen in my browsing of the interwebs, the bow should be the part making contact with the recovery point, and the pin of the shackle should be on the strap/rope side
this prevents side loading
i.e. in your video example, the shackle is connected backwards
for a dead straight pull, this shouldnt matter

recovery points where the shackles attached by the pin with no other option, and where the shackles can rotate about the pin vertically but with no horizontal movement, are incorrect, i.m.v.h.o
the hole of the recovery point need to be big enough that one can fit the female threaded section of the shackle through

his accent/pronunciation is amusing occasionally, but he speaks a lot of sense

the rating of the shackle is 50% for a 90°load, and 70% for a 45°load

What you say is technically correct. However, as always there is another side to the coin. A recovery point stronger than the bow shackle but with a hole large enough that the "knuckles" of the recovery point can fit through would need to have so much "meat" that there would be almost no room left for a rope. Because if the hole is that large, the recovery point would be loaded in a very small percentage of the hole, making it more likely to bend.

Also consider that the bow shackle's rating has a safety factor of 5, much higher tha the rest of the recovery equipment. Thus a 3 1/4 tonne bow shackle has a breaking strain of around 16 tonnes. Thus there is room in there for a significantly angled recovery. And a high stress recovery should probably be kept as straight as possible. Especially on the vehicle doing the recovery, else you are likely to roll it. Actually, thinking about it, that applies equally to the stuck vehicle.

Further to this, I have long been concerned about the strength of the vehicle's chassis at the point where the recovery points are attached. I am pretty sure my recovery point are stronger than the chassis. The strength of these will also be significantly reduced if the force is applied from a steep angle.

But the point of this thread was to consider the point of attaching a soft shackle to a bow shackle. To me that makes no sense at all.

agree with you pete, there's no sense whatsoever, other than the convenience of speedily attaching the snatchh/pull strap, as one doesnt need loosen and remove the bow shackle pin.

fair enough
it seems that the bow shackle then in this case is considered by the owner/driver to be the recovery point, one which is able to swivel
i would imagine it is a mostly permanent fixture

Ja, its counterintuitive:

The soft shackle was designed to be safer than using bow shackles but his recovery points are too sharp for the soft shackle, so he's using the bow shackle as it carries a smooth radius, so we back to using bow shackle, its just so silly.
