I rarely ever choose a line based on how visible it is to fish. I feel it’s very overrated. This is my personal experience. In fact, I always gravitate toward high visibility lines.
Regarding braid over mono, there’s pros and cons to each.
Braid
Pros
No stretch, great for deep water
Extremely sensitive
High visibility to the angler
Sinks
Small diameter
Long life
Cons
Ices up in cold weather
Expensive
Need backing
snags on ice easily
not extremely durable
Can’t use with a bobber
Mono
Pros
Resists ice up
Doesn’t snag on ice
Resists abrasions
Inexpensive
Use with a bobber
Cons
Floats
Stretches
You need to decide what you need for your situation. Some of the pros can be cons ( and vice versa) in some situations.
Braid is on most of reels and I always have a mono or fluoro leader.
