getsome, I don't flyfish, so can't help with technique questions... what I do recommend is that you try using the 'search' button at the top of the page and do some looking around through the old threads because I know there have been many that are very in depth regarding the subject.  I have spent literally hours doing nothing but reviewing past forum threads for info and it is helpful!
 Good luck on your endeavor and have fun!

Trackerz -- It's just a nice, uncomplicated, rhythmic help to keep the cast from getting all fast and jerky. On "Edel" I go from start to 1:00, followed by a little pause (just like the song) to wait for the tug, then "weiss" is the forward cast. The song has perfect timing for my stroke. In A River Runs Through It, dad taught his sons using a metronome. This is okay but seems too mechanical to me, and besides I'm not adding a metronome to my vest . . . a man's gotta draw the line somewhere. Edelweiss also works to help slow down a golf swing. Obviously, I favor moderate/progressive action rods. Try it, you might like it.
