I've strengthened my VIT on my PLD, unfortunately this means putting aside some of the AF gear which looks awesome but has terrible stats. With only AF gear (no accessories) You have a pretty sad DEF 630/VIT 275. With my mixed AF set up, no accessories, it's DEF675/VIT314 So, not all that big of a change (not even capped) but it makes it easier to stack enmity with accessories and Materia without sacrificing DEF/VIT. Maybe someone can post an optimal set up for the current PLD, I know I don't have it and I would like to know what it is.
