When I got my jolder's hammer I think I got a pretty good base one. CQB ballistics, Smart drift control, Soft ballistics. Spray and play(nice to let it run down and reload twice as fast) Perfect Balance, Field Scout, Quickdraw Reactive Reload(isn't really worth it with the slow reload time) I use Field scout and smart drift control, the 50 shots in the mag are amazing and allows me to chew through enemy teams in iron banner
