hNt,
I cannot help you with that question because I never use an indicator and I nymph fish 99% of the time. What I will do for you is help you with fishing without an indicator if you care to make the trip my way. That way you can decide which way you wish to fish. I just do not care for indicators. I would much rather concentrate on the end of my fly line and let it be my indicator. You may decide you need to use indicators and that is fine. Now, before someone posts on how many fish I am missing because I do not use an indicator, I really do not care because I am happy with how many I catch without using an indicator. There is nothing wrong with using indicators, it is just not something I care for. To each their own...
Come fish with me and we will give both a try...
