Consistency in weapon DMG/DPS

[fash]

Since you're specifically interested in slow 1hs, also consider that your offhand swings no faster than your mainhand. If your offhand has relatively low delay (& presumably dmg) compared to your mainhand, you may get better dps from your offhand by switching to a slow offhand with higher dmg. (Double check the dual wield mechanics with someone else, I've very little experience playing a melee char)
