Reason we take to much is because we have too much!
Be ruthless! I take a rucksack/seat combo, 12' general purpose rod with a tip ring that can take a quiver tip, couple of rod rests, reel with spools of two and five pound line, a few floats, landing net, baits, a few legers, copuple of feeders, , disgorger hooks and shot. All fit in the rucksack with room to spare for sarnies, flask and waterproofs.
