This is a strong xin day master with strongly rooted self stars. When the resource earth star is in the stem, the officer fire stars will not be able to control the metal stars. This means that the strong xin day master can only be weaken by the output stars. Unfortunately, the output water star is not in the stem.
You can guess that the best luck pillar should have water star in the stem. Ren-chen or gui-si?
In the ren-chen luck pillar, there will be a shen-zi-chen positive water frame. However, the chen will destruct the chou and harm the mao. In the gui-si luck pillar, the si will combine with shen and transform into water stars. Since the si has no negative relationship with the natal chart, I will choose gui-si as his best luck pillar.
