Forogot to mention the following indispensables:
1) I'd like a fine, thorough discussion of the dual, for instance, integrated in the main body.
2) MUCH austere stress on accentuation and its application.
3) Variety of ancient authors in the reading passages.
I know no book which meets all the requirements you give. The Hansen & Quinn Greek: An Intensive Course
(a modern text; not available on Textkit) does the best job in getting real Greek from a variety of authors before the student quickly. Someone comfortable with Latin is not going to find anything too surprising in this book. The dual is not well integrated. Vocabulary comes quickly.
For texts here on Textkit, William Smith's A First Greek Course
moves quickly, and the dual is used from the start, but gives no wild Greek, only lots of practice sentences. And lots of vocabulary, mostly preparing you for Xenophon, it appears.
Clyde Pharr's Homeric Greek: A Book for Beginners
is mostly authentic Greek, but only Homer of course, the dual is not only presented but occurs in the texts. The vocabulary is only that which occurs in the first book of the Iliad (611 lines of verse), but this is provides a solid foundation.
You need to decide which of the indespensables is most important. Each textbook author writes to correct some failing of other books, but usually at the expense of some other area.
