Which combo should I go with: Roar Bahamut Giga Drift-10 or Guilty Bahamut Giga Metal Destroy-4?

Also, does anyone know of any good Balance type combos? I’m debating using Astral/Zest Bahamut/Achilles Giga Destory’/Metal Destory-10 but am not sure if it’s competitive.

Roar combo is the better combo of the two you have listed. Guilty really wants/needs a rubber driver to function properly.

Balance isn't really a thing in BST unfortunately. Destroy in general is outclassed by other LAD drivers and by Rubber attack drivers.

Also, for future reference this should probably go in Build Me A Combo, this kinda stuff is why that thread exists.
