I just ran the Menagerie for the first time in like a month (I'm hunting a Trust with Explosive Rounds). I got five Trusts from the chest. Looks like Menagerie is worth running again if you're looking to grind out some rolls.

EDIT: I got my Trust. Snapshot Sights and Explosive Payload. Extended Barrel and Range Masterwork. It honestly doesn't even feel fair. I've always loved Trust. My Outlaw, Zen Moment Trust has served me well, but this new one feels like its on another level. Luna's Howl might go back in the vault now.
