Favorite Praying Mantis Book

[Tensei85]

Just wanted to start a thread on what everyone would deem to be excellent Mantis books for practitioners or just general reference.
Again appreciate the input.

I found the WHF 1-16 (cult classic) useful for personal reference and basic idea of how to demonstrate the forms, however some of the angles and spec's are left out in the writing. But it does list the names of the movements which I found helpful to at least get a basic idea of the meaning of the techniques.

I also thought the Lee Kam Wing book for 7 star praying mantis (vol 2) was very good for reference. It lists the Sap Sei Lo Tan Tui, Dou Gang, Cha Chui, Ha Fu Ga Chou etc... Which is definitely good for reference for advanced pract's or beginners alike.
