Best to figure your build out, and then gear for it.
That's really the best advice.
So for the OP, my recommendation is keep the Skorn and shop for an attainable 1H/OH combo as you level up to 60. If you are gearing up on a budget, you will probably find that Skorn gives you the highest DPS options initially, but that 1H/OH begin to close the gap as you improve them along with the rest of your gear. And if you're rich, just keep the Skorn because you can. :)
At that point, the tradeoff will probably be between the higher LS and fewer mana issues with Skorn versus the versatility and agility that 1H/OH provides (e.g. using String of Skulls OH so you can swap out one of the other Zuni item slots but still keep the mana regen set bonus, leveraging the ToTD vaccuum effect, playing with ability bonuses like SB dmg bonus or Bears cost reduction, or trying a 0 dogs build if you can afford the gear for that).
IMO, that is one of the best parts of the WD class. There really are a lot of very different build options available that can each be effective. And there are a lot of opportunities to use different gear for different builds, with overlapping synergies. At least for me, personally, I find that the other classes gravitate towards a much more limited set of de facto builds.
