Fully agree with PaQ, about carefully planning and knowing in advance what you do.

Here is also (once again... :-)) a very good example of the ZModeler brush:

I wonder how many times fillets etc. would fail on such a complex model and if NURBS
modeling would be really faster than subd modeling. One other advantage is also dynamic
subdivision (rendering), so that poly count can be kept low when saving, compared to a
frozen subd mesh.

Pixologic must had a good reason to implement the ZModeler brush in 4R7... :-)

But i agree, one should use the tools one is most comfortable with.
