Rivers are a totally different matter to lakes, continual flow in most, the chances of debris coming down with the current rubbing your line up, playing fish round potential snags that compared to a lake, you know nothing about.
You want a decent line with good abrasion resistance, and you may need to consider the distance you fish, a thinner line will get less line pressure from the flow, meaning you can use less weight to hold bottom. Casting upstream or downstream makes a difference as well❗️
For river fishing I would be using Daiwa Sensor in brown, or Gardner Pro, light or dark.
I actually landed a 28lb river carp over brambles, thick weed and rushes on 15lb Sensor in about 4minutes flat. I stopped the carp getting its head down towards the snags in the middle, and only had the nearside brambles to contend with before netting it.
Sensor was a line I totally trusted, although only in brown.
