I agree with Nyorin's assessment 100%.

I learned Greek and Latin roots when I was...I think 6th or 7th grade. It improved my understanding of English exponentially, and I use those lessons, probably daily.

Imagine learning Greek and Latin roots at the age of 5. Not so helpful.

That's how I see Heisig method. It has useful things to tell you, but you start putting up wallpaper before you have put in the insulation.
