I used the hi vis yellow line @ and watching for the line twich method on sea trout the other day. It worked good I used 8ld. hi vis instead of the 4 ld. I use on crappie and got 7 sea trout @ 2 flounder . I was casting 1-8th jig with 4 inch gulp pearl swiming mullet. I started using hi vis line from reading fish docs post on the VA. board. I was fishing the jetties at Lewes DE. .
