I was thinking about making a floating tip for a new Airflow Skagit head from a SA steelhead line that I accidentally chopped in two a couple years ago. There's a table in the box that gives some weights for sections and tips as a guideline for making tips. Are those weights in grains or grams? I found another table online that uses the abbreviation gr. on a weight column, but that still could be either grains or grams.
