I'm not sure I can answer your question on the weight to strength ratio, Chris. I can only say that among trebles, the strongest one in my experience for its size is the ST-76. I've seen pretty much every hook (both single and treble) used for GTs straighten at some point or another. Tak Otsuka managed to straighten a Jobu 9/0 and a Shout Kudako 7/0 on the same fish. Clearly, the fish was able to exert pressure onto both hooks and they gave. I think in the scenario, most hooks, especially the trebles, get compromised.
The lures that are most sensitive to the weight of the hooks are surface stickbaits, especially lures like Carpenter Gammas. That's why I use ST-66s on them. Sure, you can use heavier hooks but it does dull the action of the lure.
