So I got this Rio nymph line. Can someone explain to me exactly how it works, or what about it is better for nymphing? Should I fish it differently? Someone once told me it has to do with the hook set. But I still need an indicator, right? And if so, the sink-tip aspect wouldn't matter, right (since the line would float at the indicator)? I am just confused and any light shed on this would be great (or if there's another post regarding it, just point me in the right direction).

Thanks much
