The best weight for a kayak paddle really depends on the paddler. A lighter paddle will be easier to lift out of the water and can help reduce fatigue, but a heavier paddle can provide more power and might be better suited for larger paddlers or those paddling in windy conditions. Other factors to consider include the length and width of the paddle blade as well as the materials it's made from. Ultimately, it's important to choose a paddle that feels comfortable and suits your individual needs.
