Here's the thing:
PG actually scales, so even with CR assistance you can make it unnecessarily tough. The "sweet spot" for gear is like ilevel 630, give or take. When you scale up gear to around 700ish, the difficulty scales up dramatically as well, to the point where some classes have a lot of difficulty doing it.
My advice would be to use Enyo and a good CR yourself, but "dumb down" your gear for it. The tuning in PGs is really, really bad.
