write down your stats go buy one chain whip and see what the stat gain is, do the same with one item from each category. when you are done you will know what kind of item gains the most for you. most likely it will be vehicles or armor, then look at the spread sheets (search best of the best on forum) for locations in the maps for items to "farm" to raise your stats... or just go buy a bunch of gold and spend it on crates and go kick the dudes Butt!
