That is not the issue here.
CaseyP did not say that it was a saltwater tropical line. He stated just that it was a saltwater line.
The normal saltwater line is made for coldwater conditions and will work well. The only problem might be that it will not float as high as a true coldwater, freshwater line because the saltwater line is designed to float in a saltwater environment which needs less floatation than a freshwater environment.
