Re: How to fish a hopper, and some rigging questions
The difference between the powerflex and the fluoroflex is that the fluoroflex is a fluorocarbon while the powerflex is monofilament. For all intents and purposes at the beginning level there isnt a whole lot of difference between the two given they are the same diameter. Some of the advantages of fluorocarbon that help to justify the extra cost are that one, it is slightly more abrasion resistant, it is invisible in water because the refractive properties of fluorocarbon match water and will sink. Mono will be slightly more limp however and it will float which can make it better for dries while the fluoro will be invisible and sink making it better for nymphing generally. Obviously there are other factors but that should cover the basics.
Also, as far as the adjustment of the indicator and weight. Its a good idea to keep indicator length about 1.5-2x the water depth you are fishing from the indicator to the weight. And dont be afraid to keep changing the depth! Then space the weight about 12-18 inches above the point fly and the dropper around 12-18 behind that. Just a general nymph rig that you can toy with and adjust to your waters!
