Neil Ohlenkamp has managed to combine superior, clear photography and thorough, detailed explanations for huge number of techniques to a reasonable size book.
I liked the detailed pictures showing hand positions and the fact that he shows a number of variations for most throws. The variations show competition oriented and some rarely seen ways of doing the same throw. This enchances the learning experience guite a bit.
There is lot to read and learn about the principles behind the various waza so this book is a definite buy both for beginner and serious practitioner.
Best of all the paper is good and the price was low, so highly recommended.
