UVHM leveling problems

Just beat campaign on UVHM and im currently level 59.7 ish. now i really want to get to 72 so i can grind op levels but leveling is just soooo slow. what should i do to get to 72 now? havent done any dlc and barely any sidequests and i really dont want to reset progress until op8 cuz i dont wanna get burnt out/ dont wanna do it all again.

so, any suggestions? how did you do it?
