I used to do a whole lot of ultra light fishing, using 4 and twp pound lines. NEVER again!The new braids have been the answer to line stretch, and poor hook sets.We used to troll rapalas on lake michigan at night for those hugfe brown trout, in shallow water. 50yds of light line, and a long limber rod were the tools you needed, and many a fish was lost because of poor hook sets due to long line and the stretch factor. I'm too old to go back there now, but I know that there are guys using the new lines and doing very well.
