I've always stuck with splinters, even much before it became a well-known build. Blizzard halving attack speed made it much more difficult to run this build, but I still do and I find it much more fun than using vision quest.
I use a mojo with +13% poison dart damage (http ://us.battle.net/d3/en/item/zunimassas-string-of-skulls), and I stack intelligence, all resist, vitality, life percent and attack speed as well as some extra critical rate/chance whenever I can work it into my gear. I'm currently at around 50k dps with 600 ~ 700 on each resist, and I have nearly 50k hp. I've obtained all of my gear for less than 2 million, which I've gotten just from running through the game the first time.
I like to use items with good move speed bonuses (so far I'm using 12% speed shoes as well as Tyrael's Might, which is a 12% speed chest item). These items are great for kiting, and they also make spirit walk much faster.
The strategy is basically running in with spirit walk, using soul harvest on a mob and kiting all the regular monsters away from elites and champions (if there are any). I slow down everything and pick off the easy monsters first. Then I wait for a good opportunity, and collect all the health orbs and use Big Bad Voodoo to finish off the harder monsters. If they're too difficult, I just simply kite them away, dealing damage while also avoiding their attacks. Big Bad Voodoo has a long cool down, so I always save it for elites, champions and bosses. The zombie wall is a great way to attack from far away without worrying about being chased, and while staying out of the range of most attacks.
