#fishing gear

so i just got my hands on a penn international 50tw and im trying to figure out how to set it up for deep sea fishing anyone have any experience with this reel? i was thinking of using a 20lb monofilament leader with a swivel and a circle hook but im not sure if thats the right way to go i dont wanna lose any big ones cuz of a crappy setup btw does anyone know if the gpt-4 tomato planter overwatering issue is similar to when you get too much water in your reel?
