Thats called the 50+2 method......well with a line counter reel let the lure out 50ft then clip on a 2oz offshore snap weight or similar type then continue to let out line until you reach a total line out of the second number which by what you posted 160ft and 135ft..normaly a bandit deep walleye goes down 21ft at 150ft of line out but with the snap weight greater than 40ft are easily gained and the leader length of 50ft wont spook fish...download the precision trolling app and watch youtube videos talking about the 50+2 method and snap weights
