Stop trying to turn this into a pro powerlift thing. Powerlifting does not make you a good fighter anymore than bodybuilding would.
There's only one lift that is going to have any significant impact when fighting and that is the deadlift. Simply because it teaches you to pick heavy stuff up and when trying to turn over an aggressor, that is obviously a useful skill.
But even the deadlift will only be useful up to a point. Your opponent probably won't weigh 200 kilos. Let's say he weighs 100. You need to be able to lift 100kg comfortably. Most bodybuilders will have deadlifted that weight for reps, so they are comfortable with that weight every bit as much as powerlifters.
The difference is bodybuilders, like you say, do a fair bit of volume. During any fight muscle endurance is going to matter. You might be able to lift 160kg, but the bodybuilder might be more comfortable lifting 100kg ten times. His muscle endurance is probably going to be better than yours. Because he's no doubt leaner than you too, his general stamina will outlast yours as well.
What I'm saying here does not count for professional bodybuilders though. Every one of those guys is on steroids and has built so much mass they are hardly able to move. I bet their balance is all off too and they probably fall over quite easily. That shit tends to happen when you can't walk properly.
I do not know what a lilliebridge is. Is it some kind of fat leprechaun?
