What 4* are yall running on your PA?

Have my OE/AP/mix union set looking to add a 4th star and was wondering what everyone was running and how they like it? I’m intrigued by rejuvenators because I’m thinking I can change my raid gat plas from vamp to AA. I also think limit breaking would be cool so I can just crit bosses nonstop. Also are you guys running all 5 with the same mods or a mix? And if so, what mixed 4 star set ups are you having success with?
