Review: I would like to say that I admire any one who puts in the time and effort to learn a martial art and master it. That takes a lot of dedication and hard work. So I really have a great deal of respect for Wally Jay. Having said that though, I think small circle Jujitsu is really an ineffective grappling system. And I also think that it is no good in the street. Reading this book confirmed all of my worst suspicions about this art. Buy it only if you are looking for a good laugh and have money to burn. If not, and you actually want a good book about fighting try anything in Kid Peligro's Brazilian Jiu-jitsu series. Or go buy some Mario Sperry Vale Tudo tapes. Just don't get this book!
Polarity: Positive
Answer:
False
