The leader length also depends on the size of the flasher. I usually run an 11 inch kingfisher flasher with a 60 (to 72) inch leader. If you're just starting out i suggest you buy some pre-rigged stuff to get your feet wet. I almost always run meat off at least one dipsey. You do have to run slide divers or (i) hand-line them in. It's not as crazy as you would think it is. Just need two people. We handlined a 32 lbs king (among numerous others) into the net last year. This was using a 60 inch leader and a 12 ft lead off the dipsey. Deploying is a 2-man job, also. I buy the eerie dearie strips and brine them with Pautzke.
