Aim assist is only helpful against a single target most of the time, so it would make sense to bring a Hidden Hand sniper or SoV in ToO. Know how when you're aiming at one guy and the aim is thrown off by a another guy? I personally enjoy using my Spear with Clown Cartridge, Double Down, and Field Scout. I have a chance to hold 8 rounds in one mag. That's just me though.
