I guess it really does depend. When I go on valk runs I use holy Tao valk armor on bio and champ, works prett well. For ifrit I use Tao fire since salamanders hit so high and the archer guardians are a pain also I can survive ifrits sonic blows. A few flee stalkers use it. I guess it depends on what your going to do with the Tao. I prefer champ, bio and HW for Tao since champ and HW have low hp if you run no vit at all
