Acid would be better, if it always proc'd. I've proc'd on a lot of mobs in abyssea, can't say I see the same damage returns off of it that I see outside Abyssea though. Maybe the higher defense of the mobs makes it not as noticeable of an effect.
As to the OP, I'd bet inside Abyssea, it's a better item to use than the DW boomerang, but it seems silly to switch it out. I'd bet to get the tp back that you lose from the switch, you'd waste the extra attack rounds you gain with the dual wield in place, therefore making it pointless.
