I like KBs for a lot of stuff. One being that I deal with fairly persistent lower crossed syndrome considering I sit at a desk way too much, and the swing and snatch are good to help offset that, along with work on the hip flexors/quads and ITB.
The other is that I am able to press in a more natural line given flexibility level, past injuries etc than with a barbell.
Loading is an issue though.
You may want to check out some info on Eat Stop Eat as well. I like it in that I just don't eat for a day (I choose a day where I'm busy) and can go about the rest of the 5 or 6 days I am eating without any trouble.
And if you don't think kettleball squat cleans are difficult, I say, step up to the med-ball
