You have AKQJds your opponent holds A23K the flop is QJT

And if the flop is AKLr, now who is freerolling who? (note that there are many more AKL flops than QJT flops, even if two people are holding AKxx...). There's a reason that A23K is considered excellent while AKQJds is merely good.
I also disagree with the general point (if I read you right) that you need to play tighter in PLO8 than in LO8. The greater implied odds in PLO8 make speculative hands more playable, though not by as great a margin as some people seem to think.
