Exactly right Tim. Saving $20 on a snatch strap will be insignificant if it fails and someone gets injured or killed. Recovering a stuck vehicle is dangerous, ALL recovery gear gear must be good quality with the correct ratings to do the job.
This might not be what you had in mind when starting the thread, but it might be a help.
Seems that “spot the dummy” is popular. But what is a safe standard recovery “system” ?
I’ll jump in the deep end and put up what I think is a (general) minimum and others can pull it apart, add to it, etc. so the result might be a safe and practical (not perfect) system –
1. Two 4.5T rated recovery points.
2. Each end of a 9T rated bridle chain or strap is fastened to a recovery point with a 4.5T rated shackle.
3. One end of a 9T rated strap (say 10 metres long) is fastened to the bridle strap or chain with a 9T rated shackle.
4. The other end of the 9T rated strap is fastened to a rated 9T synthetic winch cable with a 9T rated shackle.
5. The winch cable passes through a 9T rated snatch block that is fastened to both ends of 9T rated tree protector with a 9T rated shackle.
6. A “winch blanket” hangs on the winch cable and another “winch blanket” hangs on the 9T rated strap.
That system would not take a lot of time to set up and would offer safe working for a majority of recoveries.
Why 9T ratings? Covers difficult and easy recoveries – huge generalisation I know, but had to start somewhere. If 9T is too high – a possibility is to work to 4.5T total load for the system.
The 9T potential load is split between the winch (say 4.5T) and the recovery points (say 2.25T each) – all you need then is a tree or another vehicle (harnessed to a tree) to withstand the 9T that may be applied to the tree protector.
Thanks everybody for the info. I was going to ask the same question about this stuff. I've got it all, but don't know if its right.
I definately know my recovery points are up to speed, but need to go through the rest.
I'm going on a beach holiday in about 5 weeks, so it's very appropriate. Thanks again.
Take care out there.

9 Tonnes... Holy Cow, what are you planning on recovering... road trains.
The size of a 9 tonne rated shackle alone makes them almost prohibitive to carry in a Patrol. 4.2's are plenty big enough and a 9 ton snatch block allows doubling the pull
Given that most winches are 8 to 11 thousand pound (4 to 5 ton ballpark), Patrol size vehicle snatch straps are technically supposed to be no more than 8,000 Kg breaking load and Bridles, Extension straps are up to 4,500 Kg... 9 Ton equipment all through is waaay too much IMHO.
Rigged correctly for recovery you can easily get in excess of 9 tonnes pull with Patrol size gear using blocks, shackles, straps and a winch of 'standard' size such as a Warn XD900 or Tiger 12,000

Dolphins are so smart that within a few weeks of captivity, they can train people to stand on the very edge of the pool and throw them fish.
1 Snatch strap (8,000 KG )
1 Bridle (4,500 KG)
2 Bow Shackles (rated min 3.7 but 4.2 preferred)
1 Drag Chain
1 pr Gloves (drag chains can pinch like a bitch)
...if your vehicle has a winch add
1 standard tree trunk protector (12,000 KG)
1 standard winch extension strap (4,500Kg) or rope (equiv or better than winch pull rating so around 4,500Kg min)
1 snatch block (9,000 KG)
2 more shackles for rigging the block etc
IF I am solo vehicle I personally carry more than that in the form of another extension, 2 Blocks instead of 1 and extra shackles but IMHO the above is what qualifies as a "basic" kit. The extra's are so I can use a redirection as well as a pull because you don't have the luxury of positioning another vehicle in just the right spot and Murphy (the mongrel) will surely have killed off the only suitable tree for a straight pull.
