What weapon for arms?

[Kamahalan]

I'm stuck at work for a while longer but I've been thinking about the patch all day and I've got a question for any that have tried arms on the ptr or are far more knowledgeable about the theory crafting than I am. I've been fury since I started raiding in Wrath but I'm gonna go arms as it was my favorite spec back in the day. I have Armageddon out of Naxx-25 and the Titansteel Destroyer (crafted) as my weapons. Is it better to use the Titansteel Destroyer for mace spec even if it is a worse weapon or will the damage on Armageddon make up for the crappy sword spec?

If PVE i would use the sword only until you get an Axe or good polearm, then ditch that shit, Pole/axe spec is win for pve

I'm in a similar situation, I got Armageddon and Colossal Skull-Clad Cleaver, and I did some tests on the target dolls on the PTR, and got about the same dps with both weapons (as arms ofc) but have a hard time choosing which weapon to use...
