Dances with Bees
I really dislike definition. Just because it really messes up the abdomen muscles and requires a lot of restore/smooth in that area. And, if you have buttons, it wreaks havoc on them.I tend to add aged to arms and legs, but it's not essential.
I use Chubby and Pear (in addition to Bulk that Glitter mentioned) quite a bit.
I rarely ... if ever ... use SuperModel or Voluptuous.
