good job on the slay day, bobberdown... were you fishing high or low? i'm thinking of heading out to the sandy...
that's the idea... so you're not dragging the hook on the bottom causing it to snag instead of drifting with the current. so keep the leader short enough that the corkie/yarn doesn't drift above the fish.
yes... slinkies, lead, split shots... whatever to get the corkie/yarn to the bottom of the water column where the fish hang out. the weight can be anywhere between the main line and hook. the length of your leader is determined by water clarity, temp, color, etc. 18" - 24" from the hook would work. you can always go shorter or longer...
(sorry for the hijack.. just trying to answer a newbie question...)
