I use a split routine a lot of the time and I use pulls/legs and push/stomach splits.
So I work the legs, back, bi's on one day, and chest, shoulders, tris, abs on other days.
You can do whatever you want though depending on what exercises you do. I would figure out what exercises you're going to use, and then split depending on that. For instance if you were doing a push press, then my split wouldn't work for you. And since I do a lot of cleans, that's the exercise that really dictates how my routine is split.
But you're going to have a tough time not working out your tris when you work out your chest, and a tough time not working out your bis when working out your back.. so those are muscle groups you'll want to keep together pretty much all time.
