I agree with profcake. I also think the kind of theme plays a huge role in how many ips or abs you need - not just the cap level. For instance, a theme that favours hitting (such as a coors type theme) would mean more ips and abs than would be normal for your given cap.
As a final point, remember that the WISC themes are often very restrictive - which generally means the hitting won't be as good as an open league team for a given cap. Do with that information what you will.
