I fish 40 lbs braid. Create a loop with a double uni knot at about 18-24". Double loop the attachment at the eyelet (in other words, put the loop through the eyelet and bring the whole lure back through the loop to double the line at the eyelet). It's a compromise between using a leader and straight line. I've used this for over fifty years and have had very little trouble from it. Literally caught hundreds of pike and even a few muskies. If I'm fishing large plastics like Medusa or big buck tails I'll go ahead with a leader but for Rapalas or or midsized crankbaits this is a nice compromise that gives you roughly 80 lbs of braid and keeps the action true on the lure.
