Hi all! I didn't really take the time to read the whole thread, so my method of distinguishing freshwater from south seas may already be addressed, but I look for the sheen. White SSPs definitely have a satin sheen to them. Beading quality freshwaters have practically no luster to them, while the higher quality freshwaters have a reflective quality to them. Telling the difference between GSSP and freshwaters is easier because it's easier to spot a dye job.
