Most people run the P10 cranks at 20/20,30/30 but when it comes to adding weight between various leads it becomes difficult to pinpoint the actual depth.Most guys say that you get 4extra feet of depth per ounce of weight.So 2oz would add 8ft of depth.So total lead of 40 ft would put a bandit down 12ft and plus 2oz adds 8ft for a total of 20ft.But there are other variables such as speed or even the location of the weight.Going really slow makes that lure go deeper than most think.
