Ideal Time of LSAT Flex?

Hi! I'm taking the LSAT in April, and I'm trying to think ahead to what day/time of day I'll want to take the test when it comes time to sign up. Does anyone have any advice/recommendations? I've read before that it's better to take exams in the morning, but I'm also not a morning person so I'm not sure that's what will be best for me. Would love to hear about other people's experiences with the flex! :)

Edit: I guess it would help if I actually had a typical time of day that I take PTs
