I have a copy of Crabels work. The Taylor Trading Technique, George Taylor. Linda Bradford uses these two styles heavily in her work refernces can be found in her book Street Smarts. In my opinion they are excellent and have given me intense insights.
tasc is a brief summary but to the point so I'm told. The book is 200 odd pages so far more in depth do not buy it though unless you are wanting to collect it $1000.00. You can get copies of it out their on pdf format.
