You will love HOD.
I have used SL in the past. It was very difficult to use 2 cores and we would have to do 3 or more cores later.
I had planned on coming back to SL for High School, but have changed my mind.
We are managing to do:Little Hands to Heaven-lightly
Preparing Hearts for His Glory and Beyond Hearts For His Glory daily.
My oldest is doing Illuminations put out by Bright Ideas Press, instead of SL.
One thing about SL is you spend so much time on history.
HOD has everything scheduled and it all coordinates so well.
HOD seems so much more complete, while Sonlight does have great books, it seems more jumbled.
Everything is much more organized and you don't have to have a binder for the core, science, LA...
it is all in one book.
