I'm the village idiot when it comes to jigging so maybe my comments come from my complete ignorance in the sport but to me, I feel like I am missing something here.
I mean, if I look at a combination of PE6 (or PE8 for that matter), 50-70m depth and let's not be too ambitious and say a 50kg doggie, that all equals recipe for tears in about five seconds? I have been dusted more times that I can count in the past using PE8 and even PE10 in water that depth where I was simply a spectator. The doggie did whatever it wanted to and I was simply there for the ride hoping the damn thing wouldn't cut me off.
I wasn't completely stupid though and worked out that if you found a really deep spot or ideally, something around a sea mount which dropped off really deep, you has more chance on a fish and could actually fish PE6. Unfortunately, the stupid things died and I stopped fishing for them as a matter of principle.
Personally, I don't really subscribe to the issue around stopping power in a rod when you're fishing for
doggies of any decent size. A 100kg doggie is an unbelievable beast and I want to emphasise that. They are an absolute monster of a creature and I am astounded that we can talk about just knocking them over in quick time. Trying to put the brakes excessively on a decent fish just makes them panic even more ensuring a harder fight (assuming you stay connected) and a dead fish. When you land a really big one, its 80% luck - and its dead.
I can't apologise for being so negative about dead fish because this forum promotes catch and release. Noone who goes fishing for doggies should be under any illusion that the majority of the fish they catch are going to swim away.
