Your rig I would not change much on a 115Penn I would use 65 or 80lbs braide unless you get monster fish ... I have 1500yds of 65lbs on my penn 115H and does a great job for me Manually).. I can hold bottom in 600-900+ ft of water with 2-3lbs of weight depending on how strong the current ! you have some nice pic`s of fish !Nice catches

If you fish in deep water 600 ft or more ,there is no
light ! it`s dark so you can probably catch the jobfish at night ,also if you fish that deep add a strobe
light to your rig ,you will catch more fish ,here we have a saying ...NO LIGHT NO BITE!
