Great post. Enjoyed it with those nice pics. Power pro produces a line called depth pro hunter. It is a multi colored fishing line. Every 25 yards is a different color with blk marks every five yards. It has four main colors so when you come full circle you know you have 100 yds out. Might try a spool. If your spools are large compacty, fill half the spool with cheap line and then finish the spool with depth hunter. Connect the two lines with an Albright knot.
