I have this line in WF6F that I use on my Sage Z-Axis 9'6" 6 wt. It casts good but for some reason I cannot keep this line floating. I use their recommened "Whiz Lube" and it will last maybe an hour before needing to be reapplied. It has lots of memory in that it lays in a continuous "S" which is not bad if you are fighting lots of drag, but I usually use this line on stillwater and I generally would prefer a straighter line. I'm going to give it one more season to see if I can figure out how to make it perform up to advertising. That's it so far--.
