I brought a couple haven't thrown them yet. But when I buy tungsten jig I buy them because the noise they make when they bounce off rock cant be matched by a lead head jig. Most times they key off that noise and will get bite when a lead jig won't get touched. It has happened plenty of times fishing with my friend, when I'm smoking them and they aren't getting a bite using the same color. Soon they will be asking me for a tungsten jig!
