Nothing like it...
I go through extended periods trying to convince myself that nymphing is for me; that it's a technique I could be content using for most if not all of my trout fishing. It's challenging, effective, and (arguably) down right exciting at times. So I stock up my selection of nymphs, and I re-read my books on subsurface fishing.
Then it happens... I stumble into a hatch, and a rising fish. My pulse races and I fumble through my box for the right fly. The fish rises again and I drop my first fly in the water because my hands are shaking. I get the fly tied on and as I nip off the tag end of my tippet I realize I nipped off the standing section, and I have to start all over again.
Finally, the fly is on, the presentation is made and with a mad leap the 10" rainbow comes out of the water as my fly drifts by. My hair trigger reaction is to jerk the fly off the water into the trees behind me. I break it off and start again. After the third cast it all comes together and only then does my pulse fall back into double digits.
There is NOTHING like casting a dry to a rising trout. For me it's what trout fishing is all about.
He is risen (They were rising)
He is risen indeed! (They were rising indeed!)
