County Tree Question

Does anyone know if the Epiphany and either the Perfection or Fusion are on the same tree? My horse’s Epiphany isn’t fitting well, and neither are any of the other 4 in our tack room (all relatively new). However, the Perfections and Fusions (all relatively old) all look better. I’m wondering whether it’s a panel/new design issue, or a tree issue, as I greatly prefer riding in the Epiphany. Thanks!
