[url=http://www.flyfisherman.com/:2d82f]http://www.flyfisherman.com/[/url:2d82f] has a couple of videos from the "Best of the West" competition.

They were casting commercially available 5 weight rods with a Scientific Anglers XXD line. The winner was Jim Gunderson at 120' something. Steve Rajeff was a few inches back. You can read it for yourself, but Gunderson used a Powell, and Rajeff a Loomis.

Whatever, the most interesting thing is the contrasting styles of the two casters as demonstrated in the video.

Download the videos and see what you think.

I conclude that you can get to the same place in different ways.
