Except the videos at trainingroomfit don't have teh same movements that happen with a barbell. For example, that's the worst video of a clean (and press) I've ever seen. Maybe that's how it's done with kbs but since most of the trainees here use dbs and/or a bb, it's not really applicable. Now, I'm not against kbs at all; I just don't think they're the be-all-end-all that some do.
On a side note, I noticed the other day that our throwing implements look a lot like kbs with chains on them.
