graceonly,
The ladies are already doing a great job of answering your questions, but I will post a link to a thread that will help explain our experience with First Language Lessons as compared to Rod and Staff:
viewtopic.php?f=6&t=3963
While you can easily use any grammar program you desire with our guides, using First Language Lessons and Writing with Ease daily will definitely add time to your day beyond what we are allotting for these subject areas. If using either of these programs causes you to skip portions of our oral narration, written narration, writing assignments, or story discussions it will also affect the flow of your HOD guide (depending on which portions you are skipping).
As far as WWE is concerned, we do cover all of the skills found in WWE within the HOD guide, but we do it in the context of what we are studying for the week. We differ from WWE in that we are not simply assigning a portion of a passage from random literature (albeit classic literature) to apply comprehension, retelling, narration practice, and written narration practice. Instead, we are scheduling and teaching how to do these skills within the context of wonderful literature that we are already reading aloud, living science books that we are reading daily within the core program, and within our already scheduled history readings. So, the topics on which kiddos are discussing, retelling, and writing are wound within our studies, rather than being a separate program. This would be the Charlotte-Mason way of teaching, practicing, and applying these skills.
Since these skills are already found within our guides, we find adding another whole program, such as WWE, to be redundant.
In our younger guides, we take a CM-style gentler approach to writing and grammar, so we will differ with the classical approach to language arts in our early guides. CM believed it was important for kiddos to first copy from excellent literature, poetry, and the Bible; to read extensively from great authors; to have a strong foundation in oral retelling; and to have a foundation in spelling and grammar skills (coming mainly from copywork, dictation, and oral narration) prior to being asked to write written narrations.
This is the approach we take in our younger guides.
WWE also focuses on writing a summary, rather than writing a true CM-style written narration. Summary narrations sum up the big ideas, but often leave out the style and flavor of the author in order to emphasize coming up with the "right key points". Charlotte Mason style narrations, in contrast, focus on paying attention to the style and wording of the author in order to write the narration in that style (borrowing wording and phrasing from the author that stood out to the reader to use in the written narration). This pays off big dividends as kids get older, because they will truly have been reading and writing in the style of great authors - which eventually pours out of the child's own pen or pencil as the compilation of great writers comes together to form the student's own style of writing.
Our DITHR program works well for teaching comprehension, higher level analysis, and for pulling out the key points of a story, so those skills are also covered within our guide. Through DITHR, rather than only working on comprehension, we are also working toward teaching kiddos to read with moral discernment. This is another goal that is not met through either FLL or WWE, and is one of the most important goals that will impact what our kiddos feed their minds as adults.
When using Rod and Staff for grammar in combination with the skills taught within our guides, we also reap the blessing of having the focus be on the Lord and His word within our study of grammar and writing as much as possible . For our family, this is another important goal, as we want the Bible to be throughout all we do. We find the ultimate purpose of grammar and writing is to portray ourselves both in writing and in speaking in a way that glorifies our Father in heaven. Using Rod and Staff helps us reach that goal, while still providing excellent coverage in both grammar and writing. When paired with the other language arts scheduled within our guides, a very academically strong, God-honoring language arts foundation is the result.
I can appreciate this discussion, as I know many of you come from a classical background. While you will find some elements of CM and Classical to overlap, you will also find them differing in some very key ways. It is the differences that are worth pondering to find the Lord's best for your family.
This past thread may be of help to you as you ponder the differences:
