I would like to play with the same level and questlines as my friend's characters, which are mostly Level 30+ and in True Vault Hunter Mode, but some of my characters that I'd like to play are in a low level and are not yet in True Vault Hunter Mode. I would also like to have all weapon slots unlocked.

I'd rather not play through the game again to be near the same level as them.

I've checked out Gibbed's Save Game Editor but I am unsure on what fields to edit or toggle to make my characters be like what I described.
