My depth of water was 40 to 45 ft balls were down to within 5 to 7 ft of bottom adjusted to fish i marked. I let out 150 ft of lina attach to release and semd it down. Then you have releases to pick pads or chamberlins also blacks i like blacks both of these styles can be set to release at slightest hit.they are Easy to adjust blacks are easiest to me. I would use 8lb ball also. 10lb if going deeper than 50ft but see what rigger mfg recomends you don't wanna break it lol. . Nothin to rigger fishing to easy.
