Got my first boat. 14' Gamefisher Jon Boat. Going to use trolling motor only till I afford to buy a gas motor.

I will be dock shooting in upper Chattahoochee river (GA) and Lake Lanier (GA). I will be fishing in the coves. 14' jon boat has no chance in the open water in Lake Lanier. Also, I will be trout fishing from the boat in lower Chattahoochee river.

Quick question, what weight jig head should I use for dock shooting? I have been practicing dock shooting in a five gallon bucket.

Thanks in advance.
