Query: Great DVD series for the beginner and intermediate Krav Maga student

This video set is a great way to keep Krav Maga concepts and combatives fresh in one's mind. In my area there are no Krav Maga training centers, and so I rely on this great video series before and after my training sessions to keep perfecting my kicks and punches. Because so much of Krav Maga is designed to be instinctive, I can usually tell when my combatives are off, and reviewing the relevant method in this DVD series really helps me work through the flaws in my defenses and keep me on track. I am looking forward to more DVD training from David Kahn, as his teaching method is no-nonsense and concise.
