fluorocarbon

I ordered some 80lb Triple Fish Leader Material. When it arrived, I noticed that it is quite cloudy and has an amber tint to it. Is this normal? Thanks.

I am going to try a fluorocarbon leader for pike fishing, but I am not really sure which brand to go with. Does anyone have experience with these two brands? Are there any better ones? I am open to any suggestions. The main thing I am worried about is how well they will stand up to teeth. Thanks.
