It all depends on how you fancy different types of fishing, for me, nymphing is the black sheep in my arsenal.
Although it is my most productive way of catching steelhead here in eastern canada it is my least preferred and the same goes for trout.
Ideally I would be swinging a spey or dee fly on a cool morning in a pool and getting that tug that I wait so patiently for, now often times when swinging a fly its them taking a shrimp pattern which is fine by me.
Even getting them to take a dry is preferred although it happens even less (I have had some hammer some stimulators though)
But if your one of those guys that are patient and stubborn like me you fish certain patterns on the swing, but if your looking to catch more fish, using an indicator rig is often much more productive
The tug is the drug
