Put 20' of 40lb test line on your reel and use 40lb or 45 lb wire on the part of your leader between the swivel and the hook. Tie the 40 lb shock line to the running line with an albright special and to the 3 way swivel on the other end. loosen up on your drag. 5lbs of drag should be where you leave it when fishing. set your drag with a hanging type scale or a 5 lb weight. Loosen your drag when storing your rod and make sure you reset it properly before heading back down. If you still get cut of chances are it is a shark bigger than what you want to tangle with on that rig. You can try going up in leader size then but I wouldn't really reccomend it. Most of the time I would be using 30 lb mono on that rig for a leader also but when you keep getting cut off you got to do what you got to do. BTW welcome to the site.
