I'm talking moss 10-15' off the bottom. I've had it work both ways but never know which way is best on any given day. I've kicked a boater's butt from the back of the boat with a pegged sinker and then the next week he kicked my butt with free sliding on an unpegged sinker while mine was pegged again. Is it more of a guessing game or is there a science behind whether to peg or not?
