Mono for riggers. I run blood run sea flea been good so far. Copper works. But i fished a month and a half straght last summer and didnt need to put a copper or lead core in the water. In the spring i would definitely run them though i do have 3 colors to 300 coppers on the boat and ready to go. I run four wire dipseys. Ran the 19 strand when it first came out lost a diver meat rig setup and wont put it on again. I do use the torpedo 7 strand and blood run and both preform well. Reel size is up to you and how much backing you are comfortable with. I run 700 tekotas on my high wires and okuma catalina 25s on my lows and have never been spooled. Biggest improvement you can make on the reels is tuna tom drags. My crew likes the 25s better then the 700s. Sent from my SAMSUNG-SM-G891A using Lake Ontario United mobile app
