All right i grew up in Idaho fishing for trout in lakes and rivers My dad always had this thing about changing colors of your spoons or flat fish which seemed to work After fishing on the pier for awhile many say do a direct tie on with your swivel and leader And i have followed this advice but i saw the coastal locks and was wondering if any one has used them or had luck i was just looking for a quicker way to change colors of my yo zuris and various other crank baits so i can try more lures sometimes i don't change do the fact i don't want to tie on a new one
