I haven't finished the series, but the instruction is outstanding. The DVD complements Couture's book, Wrestling for Fighting.
Couture covers both MMA clinch fighting & pure grappling, with emphasis on such basics as handfighting, tie-ups, and setups.

Here's one source:

Out of stock at the moment.

That's a good price compared to most instructionals.

I have his book, and like it a lot.
