Book of the Five Rings

[Disco Shrew]

I am looking to purchase Miyamoto Mushashi's book of the five rings,I was wondering if any of you knew which translation/version of the book is the truest to Musashis philosophies. In my google-ing I've found a couple versions, starting from the most popular.
http://www.amazon.com/Book-Five-Ring...8771574&sr=1-6
to the most recent and claim of accurate translation
http://www.amazon.com/The-Complete-B...8771672&sr=1-3
I was wondering if you guys could help me out with this?
Thanks.

You don't need to pay for it (since the author is dead)
