"Skagit casting came to be due to innovations to make casting efforts easier." Mumbles, right idea but not quite accurate, it came along because easier to throw half a chicken. You can't turn over an Intruder on a Carron, it just won't happen. "Why would one beat thy self to death learning (arguably) the toughest casting with a long belly traditional line if learning with new technology makes it easier, better on the shoulders or any other improvement." Because you are fishing a river that calls for 100' casts, cast after cast (Thompson, Snake, Columbia, parts of the CW, Deschutes.....) A long belly is much more efficient in these situations. Skagit isn't really new other than by term. Look at scandi lines, they have been in use for years. They are designed to turn over smaller flies, they are still a short belly line (they just have a front taper). 15+ years ago Mark B in Welches was selling "launcher" lines. They were a 12-14 wt SW line (35') with the front taper cut off. Dec, Ed and others used to cut windcutters way short. Casting a LB doesn't beat you to death, hell I've fished a 90' belly line on a 16'7 rod for a week and not felt like I was getting beat up. I had a couple of shorter back up rods that I could and would have switched to if I was getting the least bit sore. Yes, it's different than Skagit not better or worse.
