I started off just using a peel with pretty good results. As time went on I decided to use parchment paper. My reasoning was if I spent all that time prepping and getting the pie ready, I did not really want a launch disaster. Then I would have to wait another 2 days to try again. I remove the paper after the skin is set, about 3 minutes, then it stays on the stone till finish. I have not noticed any decrease in the rise of the rim or browning. Though I have thought about trying just the peel again. I have not had any problems launching with the parchment. Of course if I got a Blackstone or WFO, no more paper, and I would have to improve my launching skills.
