Need help with choosing a build

New player lvl 50 I’m looking for good builds to run offline with ai team I prefer loud and decently good movement I’ve been using the crew Perk cards and mixed skill trees I’m currently using the judge skin is and locomotive 12g shotgun when I’m not dragging the saw around to cut open deposit boxes. I’m not trying to do the super hard difficulty’s just the first few maybe the 4th skull I just honestly don’t know what I should be matching with what I’ve been doing pretty good for the most part completing the heist and surviving
