I agree with suzukimom. Writeshop will probably not be a great fit right now, because it requires original creativity, even if they do provide the topic. We were not WWE fans. My kids did not like only getting a snippet of a story and you need to “correct” them constantly to answer in complete sentences. Honestly, I found it creative-killing, boring and robotic. (to be blunt! LOL) It works great for some, but it wasn’t for us.
We use a combo of CM style & Bravewriter We read, the kids take turns narrating back (or we do this ala Bravewriter and have a “big juicy conversation”). We recently started a narration jar and the kids LOVE this.
Because he’s reluctant, I would stick with strictly copywork to start. If you want you can add in some Friday Freewrites or other Bravewriter activities. If you sign up for her emails, she sends one a day and they have awesome little activities and tips for writing, and they are free, so you can’t go wrong. 🙂
