i could use some insight and help with LL RF SR/party combo

so im currently a lowlife RF SR guardian

Current build

https://pastebin.com/AdT9RBvd


Now me and my friend wanna make a boss killing setup

me on my lowlife RF SR guardian

and him on either a occultist curse bot

OR Managuardian aurabot


now my question which do you think would be the best? for us to roll


guardian RF SR with occultist aurabot

or

guardian RF SR with Mana guardian aurabot




other possible ideas were

tripple curse LLRF SR Occultist + mana guardian






bottom line is i wanna know which would arguably be the most solid setup

within reasonable price no insane 30-50ex items etc
