I use 50# red power pro, I put as much braid I can get on the reel, I use the old penn reals they have a peg so the line cannot slip. It might be a little more costly at first but it pays off in the long run. The mono does not last as long, and if you you get the big one on I like to have as much line on the real as possible. Also with a dipsy I like to use a heavy short rod, with those big fish the drag cannot be to tight or you can bend the hook, braid does not streach, need as much line as possible. The new wallye board will hold a mag. diver, depending on weather, can use a lot of line just getting the board out.
