An Integrated Approach to Intermediate Japanese - Review?

So has anyone used An Integrated Approach to Intermediate Japanese? Here's a link to the Japan Times site: http://bookclub.japantimes.co.jp/act/en/...do?id=0741

Basically, at my University we used Genki I and II for the first two years (slow, I know), and now we're using the advanced book from Japan Times. In other words, this book: http://bookclub.japantimes.co.jp/act/en/...do?id=1039 (but these are just the CDs).

So, basically, has anyone used this book? And if so, how would you rate it?

Thanks for the help!
