I have used a variety of strike indicators over the years each having pro's and con's. But when it comes to using small nymph patterns, there is one that I like that and in my opinion is heads above the rest. Years ago, I met a guy (Barry Dombro) while fishing the Clinch. While making a trip back to the Clinch early last year, just happened to run into him again. He told me about a strike indicator that he was patenting and proceeded to show it too me. I have to admit, the approach is simple to use, quick to set up and adjust and most importantly, very effective. Barry mailed a couple to me, I have used it ever since and it is reusable. I showed this strike indicator to the fly shops down on the Hiwassee, both now carry this in their stores. You can see this along with a demonstration at strikeindicator.com It well worth the time and money to check this out and purchase for yourself. If you do, tell Barry that Doug referred you and said hello!
God gave fishermen expectantcy so they would never tire of throwing out a line.
