When I make morphs I do them right from the beginning of the modeling process. I use Lightwave and morphs are part of the original object file. It's pretty easy to make morphs when you are dealing with a 20 point subpatch object. As I progress in the modeling adding detail the new geometry is transfered to all the morphs automatically, I can also tweak them morph by morphs, going back and forth between the morph layers and the base layer, so you have pretty good control on what happens to the mesh.
