tomahawk,
nads is what I bought, once, when I was in prime shape, and wanting to keep my stomach hair free (i have a bit more than just a 'happy trail')
Oh dear god...the pain. Plus, it didn't get all the hair at once, so you have to hit the same spot over and over.
then the bleeding started. it was awesome.
and in less than a week, it needed shaving/nadding again.
In fact, a few hairs got ripped otu just tryin to spread that sticky crap out...its like, so gooey and thick its almost solid until your body warms it up.
