single pull isnt a problem depending on weight.
The hooks should be at least 10k rated, if not higher.
If you want to pull from both, get 2 10k straps and a shackle rated to at least 20k working. Those are minimum numbers IMO.
If I was buying stuff to keep with me, I would buy a single 20k strap and a few 20k shackles. I wouldnt be concerned about pulling only on one hook. Again if you want to pull on both hooks, use 2 straps, dont try to use 1 strap. Maybe there is something designed as a y type that would work, but I havent seen anything personally. A y arrangement would only work when pulling straight on, which NEVER happens when you need to get pulled out of somewhere.
