I read about a guy in another post saying he used a Z wing in place of 10 lb ball weight on a down rigger. I never used a Z wing but I really like trolling ballyhoo off planers tied off to stern cleats and have had success with this method. I know planers are limited on depth they run and down rigger drops line alot deeper but I hate the ball and trying to control it while trolling over 5 knots. I noticed Z wing makes a model for trolling at 6 knots and above. How deep will a Z wing run? Is its depth capability limited to something similar to a planer? Do they start to rise or become difficult to control when trolling at speeds between 5 & 10 knots? Would anyone recommend using a Z wing in place of a ball weight? Any advice will be appreciated. I am trying to decide if I should buy a Z wing and chuck the ball weight for my downrigger.
