I just tie up a 3 foot leader with a #2 duo lock on each end, I also use a duo lock on the end of my line. With this method you can buy these type trolling sinkers and change them out on the fly to use whatever weight you desire.

Those snap on weights are nice and all, but they seem mighty dang proud of them. The charts should still be the same no matter snap on weight or inline.
