I have been making PM pizzas for years. What I do to get a crispier crust is cook it on the tray it comes with for 6-7 minutes. You can then very easily remove the tray. You don't need a peel to get it off. I just make sure it is loose all around the edge. Then I use tongs to pull the tray out, leaving the pizza on the oven rack. I don't see why that wouldn't work for you.
Pretty gutsy flipping the pizza!
