What kind of set up are you using them on?
I use braid for jigging as I feel it really helps when the fish aren't really slamming them but gently sucking them in.When I started I kept it simple using just black jigs and trailers.They get bit everywhere I have fished them.Jigs for me are also something I use for specific cover or structure.I don't use them for covering water and searching.If I see a likely piece of fish holding structure I try to drop my jig as close and quiet as possable.I am a firm believer in a splashless presentaion with a jig also.It seems to make a big difference.
