I have been using the twisted leaders as in the video above lately and I am amazed by there strenght, and turn over. For years I used a 3 section leader for bass 60% of the leader lenght was 30lb test, 20% of leader length was 20 lb and 20 % of the lenght was 10 or 12lb test as tippet. We use 9 ft leaders on floating lines not because the bass are leader shy but because we are fishing weighted flies on the bottom(97% of the time). Most of our waters that bass live in are heavily stained to muddy with lots of timber but not much for weeds
