Hi everyone i'm super new in the world of lure building . I saw the job that a lot of you did and it's awesome . The question I'm looking to get answer today must be simple for some of you . I build some blank looking like a ss shad I want it to run shallow from 1 to 3 feet . The thing is I'm not pretty sure where to put the weight . His it in the balance spot or like I read near the lip to make sure the lip stay good in the water . Ouff seem easy to build lure bot damn it's way harder thath I first was thinking . Thanks for your help . Jonth
