Cool stuff, Pat. I think I will start using that method to repair some failed recurves and Molies I have. I know you don't back em, but I could easily patch in some linen cloth over the splice and then wrap em up like you do. The splices sure are pretty.
If I was building an all wood "horsebow" without historical or material parameters, I'd do about what Pat says. Maybe a deflex-recurve with stiff siyahs, or long semiworking recurves, and not too long, 60" on the upper end. Shooting from a horse, to my eye, does not lend itself to long, squared-shoulder draws and deep, long anchors, but I'm guessing.
