Re: wanting to compare 2 books
I have both boths and I agree with Larry they are apples and oranges. Total Aikido is more of an introduction to Yoshikan Aikido, but useful and illustrative if you train in another aikido style. Carol Shifflet's book has been helpful for me and I practice Aikikai. There isn't too much emphasis on ki exercises and does a good job of explaining the exercises in class. I like the way she describes the difference between ikkyo, nikkyo, sankyo. But I wouldn't rely on it as you basis of understanding if you don't train under ki society styles. If your Aikikai, it's better to go with Aikido by Kisshomaru Ueshiba or Best Aikido 1 and 2 by Moriteru Ueshiba.
But these are only good as supplemental training aids to actual real training in a dojo.
