You are echoing some of the same reasons why I just purchased TOG. I am starting with year 1. My oldest is 6, he went to a Classical private school for K-4 and K. We are new to HS. I purchased the lap book and map aids, but didn't purchase the writing aid. I thought that he wouldn't need that until he was older, but after looking over the intro to the year, it looks like that might be helpful. On the writing side, it says to set up a notebook, but I can't find anywhere that explains what that writing notebook is supposed to entail. Do you suggest purchasing the writing aid for that age? Also, can you point me in a direction to figure out how the writing notebook should be set up, or is that explained in the aid? I wish there was a way to preview it, so I could see for myself if it was something he needs now! Thanks.
As for the original question on TOG, I read a TON of reviews and played around with the samples before ordering it. It seems like the only people who didn't like it, were the ones who didn't like/have time to do the prep work. If you want a work book and a teachers manual, this would not be the right fit. But if you have the ability to take all the choices they give you and find what is going to be right for your kids each week, it sounds like you will benefit from it. At least that is the impression I got.
