My 11 year old daughter has worked through about 4 of the Reason for Handwriting series and we like them a lot. The lessons are short for each day, then on day 4 she gets to choose any picture sheet she likes and copies scripture on it to decorate as she chooses. She gets the work done, but gets to be creative as well, and my favorite part is that she is copying God's Word and enjoying it.
As a homeschool mom, I put a lot of emphasis on handwriting. I chose this curriculum because I like the formation, the length of the lessons, and the scripture verses that we use for memory exercises as well. I will say I think the artwork is a little elementry for the age (6th grade) but it's still a great book. I think the children would respond better to a little more mature format.
