Received a Shimano Saragosa SRG14000F for Christmas. The reel is capable of holding 600 yds/50lb braid, 390 yds/65 braid, or 315 yds/80 braid and capable of 44lbs of drag. What braided line should I put on it if I am targeting tuna in the 50-150 lb range? How much backing vs how much line, how much leader? Last question, I need a rod, any recommendations? Looking at something decent/towards upper end, thanks.
