I don't know that this is exactly a "ringing endorsement" but we switched to TT from Saxon (yet another program not favored by the intelligentsia) and have been happy. My older DYS got DYS level math achievement scores recently, too (higher than her PRI would predict) so it can't be a total disaster. Saxon was a bit crushing with the amount of repetition and the kids were saying they hated math. So we switched to TT and everyone has been happier. The chief strength (I believe) is it is a fairly low maintenance approach. It keeps the grades and kids progress along with minimal need for input from the adult. Some would find that undesirable. But it works for us. Basically, I'm a bit limited in what I can do for math right now because I work more than full time and delegate their homeschooling to someone that is very wired for humanities, not math.
