Builds that don't care about gear. So Unarmed combat sorts, Technomancers, and Mages. Also popular concealed hand crossbows, Sapphire Knives, Skin Pockets, Sleeping Tiger Armor, Ares Briefcase Shields, Smoke Grenades, Spray Paint (or a Paintball gun...), and anyone with a Van.
Seriously, want to be voted most popular runner in NT just buy a Van with a Smuggling Compartment. Let everyone carry around all their toys without any issues.
