Hi blindfoldjump,

With what you want to accomplish I would take a serious look at formZ. It has great NURBS tools along with new Sub-Division tools and the ability to change a Sub-Division object to a NURBS object in a single click.

Here are some videos for creating complex forms (using NURBS) in a previous version of formZ (before Sub-Division) and all the Sub-Division tools. Note some of the videos are for bonzai3d, which is an older subset of formZ, now called formZ jr.:

This video shows how to create Sub-Division objects and then convert them to NURBS for additional development:

I love MOI, it is a great modeler, but formZ is really cool, very easy to learn and extremely deep and powerful. It will even do animations of your models. There is a 30 day free trial of the Pro version, so you can check it out yourself.
