For a more balanced BiS, this is the one I made http://ffxiv.ariyala.com/LRGE. You have a decent 500 crit with a high determination. It exists another gear set where you can have higher DET, but the crit rate lowers drastically and imo the det gained over the crit lost ain't worth it.

As for extremes I recommend this http://ffxiv.ariyala.com/LVF9 with HQ buttons.
