Here's a quick question for everyone. I've always used 16 strands of DF'97 to make strings and cables...both 1 and 2 color. Now I've been using 18 strands of 8125. This is great for 1 color strings but what about 2 color strings and split cables???? 18 doesn't really work there???? How many strands ond what serving materials is everyone else using?????
