I have a few old crankbaits that aren't in production anymore, or are unidentifiable, and i want to know the specs on them. Is there a way to determine approximately how deep a crankbait runs, besides the obvious option of testing it out at different water depths to see when it hits bottom? I know as far as lip sizes go, its generally the bigger the lip the deeper the dive. But is that a definite solution, or are lip shape and angle a factor as well? When i purchase new cranks, i always save the part of the packaging that has the depth on it to avoid situations such as these. Also i know line type also plays a role in diving depth, but I'm wondering solely about the baits.
