Its called silver thread but its a basic clear mono. Not considering weather conditions and water quality, my experience tells me if you, yourself, do not spook trout on your approach, the 4 - 6lb silver thread will perform as well as any other line, including flouro's.However, 4lb may be a bit light unless you have streams without obstructions they can dive under. My friends and I have lost many 12" plus brook trout in Upper Michigan, even with 6lb test, in small streams when they were allowed to "run" and break you off on something.
