Fenrir build advice

Hey all, I have a fenrir and want to use it, I’m in masters right now and to find a good build for it. I’m currently running nanea and Leinani (only have one nanea though). Should I go for tarans and redeemer? I also have two atomizers, scourges, hazards, and growlers. I should have the heavy weapon for each medium weapon as well. What would y’all recommend? Also already have Bernadette and the max defense specialization running.
