That will require replacing the fly line in the reel with mono and rigging up a shooting head, and the recording...I'll see what I can do for you. No promises.
But not to leave you hanging - here's a vid of Mike Kinney showing how to reduce rebound by a big margin: https://www.youtube.com/watch?v=ipiJHAHVXVk
Lot of casts in the clip, including some single-spey casts. You can find and read his posts here about single speys done with shooting heads and weighted flies.
Thats Awesome. My favorite cast is the Poke he does at 5:56. I love that high rod stop along with the way he pokes that wedge way out in front of him. I like doing that style of Poke too. Different than Eds but super cool and fun to watch!
Very Subtle what you are talking about Vic but I see it in some of the casts. Must be the follow through Jim Jones talks about in some of his posts. Thanks for the tip, I'll play with it. Of course by that time in the cast, if its long belly casting, I've usually forgotten to do a couple key things, but I'll see how it goes!
