Steve We use the 32# for everything up to 300', then go to the 45# for deeper late summer kings. The 32# sinks at a rate on aprox, Length X 0.2. So that 300' 32# will go about 60' down. (300 X 0.2= 60') Speed, current, and what you are pulling play into that, but it's a good starting point. Blood Run also picked up a line of Braid, and has it reasonable priced right now (it is not made in china ether).
