Book: Perf. Riding Technique by Andy Ibbott

Has anyone read this book?
http://www.amazon.com/Performance-R...0/ref=pd_sim_b_shvl_img_9/102-1811898-9347305

I'm thinking of getting it but don't want to read another Keith Code book...
I'm a more advanced rider But feel like I've reached a plateau so I'm looking to improve my skills but I've read and done everything in the Keith code books.

Any opinions (especially from you fast guys) are appreciated.
