I have been using .018 stranded lines for about a year but I had been using a set of .015's prior to using the .018.
Think I read somewhere else that .018 was the size that I needed to change to but now I hear a lot of talk about folks still using .015's still.
Nothing wrong with the roll of the roll of .015. Just sitting in the flight box.
With the .018 lines at 10,000 rpms, it shows noticeably little more sag than the .015's and the .015's had some sag the last 1/5 length of line if I remember right ?
I'm not worried about passing a tournament test but I do want to fly safe, just lite ? Any advice would be appreciated, Cliff
