LOL, people who have met me here and actully worked with me know how strong I am. I'd be willing to be those firefighters couldn't loosen the seat after i tighten it down. Don't get me wrong, i'm not Arnold from Terminator, but I can take care of business. The hooks can and will be tigher and easier to use than the lap belt any day of the week.
Unless the later w-body hooks just completely suck which I kinda doubt, they should be way superior. Hard to screw up something mounted directly to the frame or seat frame. But, we'll see. All I can say from experiance is that the Trailblazers and G8s have a kick ass hook setup period /thread.
