I agree that those who usually write do not know a lot (however, there are exceptions). Usually writers tend to travel around and "experience" martial arts through others, usually by hanging onto their coattails. Personally, I found some of Marc's stuff to be on target, some way off. On the other hand Pat McCarthy's stuff is what I consider sci fi - finding the grandson of ryu ryu ko! What rubbish!

Another is George Dillman - what rot!

- but again, just my opinion. Tah!
