What are best charms for bvb?

[SkyMind]

wc lifers vs. 3/20/20's vs. ar/max gcs vs. ar/life scs.

Can someone give me a hint here, i don't know which ones are the best for a bvb.

i'd go for 20///36 sc's as life and AR are more important than more damage in the BvB fight...OW wins.
with enough fhr charms to hit 86% bp, but thats an opinion of mine.
