For a full writing curriculum is this all you need Easy Grammar and Writing Aids?

People have raved about Rod and Staff English and I wonder if I will miss out on something or if Easy Grammar and Writing Aids is not enough?

I would much rather just use Writing Aids and Easy Grammar but would like some assurance that it's enough.

You'll need spelling and potentially handwriting (for younger children).

I tried R&S in 3rd grade an used a similar product, Climbing to Good English, and I think Easy Grammar and Writing Aids are better and easier.

Thanks Pat, I prefer to not have to add anything and I have always liked Easy Grammar. I will just go with the flow and not over think!!!
