You can also check out Steve Shank's tutorial for making morphs in Anim8or. I'm working on my first piece too, and have found that on adjustments, I export the piece as a morph target, pull it into Anim8or, pull the offending polys out a little, save it. Then I load it as a morph target and it works great. It gives a lot finer control than using magnets.
