Re: If you could only have one Aikido book ?
I found the Dynamical Sphere really helpful like 3 years ago. Now when I read it I still think it's a great book but it doesn't give me much anymore. Haven't read much else.
BUT as there is now a campaign on ordering books to estonia I would take some advice what to order... what would be a more advanced level book than Aikido and the dynamical sphere was?
