I do what Redox does. Flour the wood peel, then dust off the excess (to prevent burning the bottom of the pies), then semolina. Once the pie is topped and ready to go, I give it a sharp shake to see it move. Then I launch while the Blackstone is rotating.
I fetch it with an aluminum peel.
Once I reduced my flour to a minimum and added semolina, the burning bottoms went away.
