Just remember if you get snagged with 100lb line it is a bitch to break. I have used 75lb and 50lb at different times,even went down to 40 on one trip.
Forty is a bit to hard on your hands if you get a good one on.
Raid one of the kids bikes and take the tube to cut up for finger stalls.
Hand lining in the shallows is a gas, especially when an xxos spangled picks your bait up and heads for the bricks you wont believe how hard some of those critters up there can go.
Another tip,get a hand line with a winder handle. Saves a heap of time when you want to move.
You will have a heap of loose line in the bottom of the boat ,and it will save on tangles and twist as well
You lucky bugger
