I started off with Lightning/Snow/Hope for a while, worked well... but relied heavily on staggering.

Recently changed to Hope/Vanille/Fang, and it just kicks ass. Default set up is SYN/RAV/SAB, for buffs to make Fang even stronger, by time thats done Vanille/Fang have done enough damage and then switch to RAV/RAV/COM to finish easily.
