I tried casting my 9' 6 weight rod lined with a WF11F SWT line. My strokes were slow and lazy with no abrupt stops. Roll casts were getting out to about 60 feet and Belgian casts may have been pushing 80. There was no effort on my part and I don't believe the rod was getting abused.
This is a fast action rod with a butt extension to facilitate two handed casting. i consider this a very relaxing way to fish and the heavy line will handle large flies. What say you?
