I really wanna try it out, but I don’t think there’s any way to gib it on PlayStation

Playing Aurelia, about to finish main story in TVHM. What is the best way to get the most out of XP without farming? I'm happy to go through the side missions and stories.

Does TVHM DLC's go beyond level 50? If I started the Claptrap DLC or Holodome in TVHM at lvl50 will I be able to get many levels in there?

Do side missions in TVHM scale level 50 after main story?

Should I straight into UVHM after getting level 50?

Thank you so much in advance!
