It doesn`t matter if it`s longer the main point is as long as it`s at least a few inches longer than the hooklink at a minimum,that is the main thing,as the pther thing it does is help protect the fish by stopping the line lifting scales,if you feel comfortable with the length that you`re using then don`t change it,just try and ensure that it`s kept pinned down,there are sinking ones but I still put a small bit of heavy metal putty on,just to be sure.
