I am wondering what your advice would be on transitioning my son from Handwriting Without Tears to either the Italic B or A Reason for Handwriting A. He is 6, going on 7 in June. We started with HWT before I put him in ps for K. Unfortunately, I could not homeschool him that year (k), but we all survived.

So next year, I am pretty sure I will be doing LHFHG with him and my daughter and will hold off on the spelling lists in Beyond until he is farther along with his reading.
I would like to transition him to one of the recommended resources for Handwriting in the LHFHG guide. They both look great. It seems that the letter formation in the Italic B would be an easier transition from HWT. However, I love the idea of writing Scripture and he would be motivated to do well by giving his work away. The reviews I found on the Italic B program are glowing. I love the look of it, better than ball and stick, but I would miss the Scripture. Any advice or tips for me?
Thank you! (The forums have been really helpful for me to read through to help make many decisions!)
