We have been using ELTL1 since the beginning of this academic year with my advanced Ker. Overall, I think that it is a great program if you are looking for something comprehensive but gentle in the early years. We recently switched over to WWE1 because WWE1 seemed slightly more accelerated than year 1 of ELTL (and I was pretty confident that my son would thrive with a bit more acceleration). I also wanted more freedom in the schedule to focus on the contemporary fiction that we enjoy. It's not that my son had issues with the CM/AO lit selections in ELTL, it's that I thought that he would enjoy contemporary selections more.
We may go back to ELTL, depending on how things play out with WWE. As this is our first official year homeschooling, I am still getting my bearings as a teacher and tinker quite a bit.
