I posted about Dual blades, they're really good with status and elemental attacks with the right armor skills. But since we're at the beginning of the game we wont be able to get the right skills to bring out the true potential of dual blades.

I think the best bet is to go with a powerful weapon early, then later on in the game when you can assemble better armor sets you can then switch back to dual blades and see when they truely shine.
