I think I bought this when in the guide program and really not sure why . It's a 100' intermediate running line for shooting line. Sink rate is 1.25 - 1.75ips. .035 or about 25#. Has a loop at the butt end. All my heads are integrated now, but I think for someone who has some heads this intermediate could be a very economical finish to a good line. $20 TYD CONUS or trade/part trade for another line 2-8wt.
