Hey basssj, there are several things you can do to a #7 shad rap. I have poured lead and used split shot in the sides, but the best I have found is take a 3/16" diameter icepick and poke a hole in line with the front hook hanger and the bottom edge of the lip. You want to keep it as low as possible. You should feel the lead already there with the icepick, that way you can slide right above it. If you get the hole to high the bait will have a wide rolling action and it will not dive as deep and may not run correctly either. Make sure the hole is perfectly straight, if it is crooked, your bait may not run right and probably can't be tuned. If you try to drill the bait, you stand a good chance of damaging the the thru-wire or the existing lead. You should get some 3/16" x 3/8" steel dowel pins. they fit perfect. Then add a thin coat of Devcon and this bait will suspend in 50-52 degree water with the same killer action. I have modified literally hundreds of shad raps, so I hope this helps. These weighted shad raps have won many tournaments on my home lakes of Hartwell, Russell, Keowee, and Clarks Hill. Good luck and let us know how they turn out for you. I ruined a bunch before I started getting them right.
