I'm surprised by the number of people who have discovered fly fishing, yet still enjoy fishing with other techniques. That's like if you learned to knit or crochet, you still enjoy sewing once in a while.
Of course, that makes sense if your goal is to create a garment or other textile. But if the draw to fly fishing is the technique or process of casting and reading the water, you cannot substitute one for the other.
As Paul, Akristickid, says: "I fly fish because I like it."
Not sure exactly what you're saying. I grew up with spinning (unless you had a spincast reel because baitcasters were not as popular then ). We could all go through our initial evolution with fishing in general. I started out young before I was a teenager capturing a small sunfish and putting it in a jar, looking at the beautiful iridescent colors in the sun. I guess that's what got me hooked, the beauty of the fish and wanting to connect with that somehow.
When I was a young teenager, I used to ride my bike with another kid to a local lake. I had an old Mitchell 300 reel that lasted many years, and a flimsy fiberglass fishing rod. We dug up lots of red worms on the side of the road under some leaves and either fished a gob of them under a bobber with or without split shot, or bank fished with a bell sinker and a snelled hook with a leader.
I won't go into all the phases of my fishing as I got older only to say that bank fishing was great with worms or corn at night for carp, catfish, bass or sunnies. I used to catch bullhead catfish like crazy from a good bank spot.
I graduated from bait fishing to getting more bass information, and power fishing spinnerbaits and buzz baits with my fishing buddies out on the river. These days when I fish for bass, it's all finesse and it works just fine. We were in our prime and we had some good catches though.
I'll admit when I discovered fly fishing, neither of my fishing buddies had much to say. I'd be the one to break the mold and innovate. It definitely was a wonderful world of learning, observing rising fish, getting over casting frustrations - of course this was after getting started with bluegills. I got obsessed with tying flies and got pretty good at it and that was the only kind of fishing I wanted to do then, for trout. I kept a journal of location on the stream, the type of water, observation of insect activity, and how big the fish were and what they took, what worked.
It was a great time of discovery and learning, and I tried to get out on the creek I was learning on as much as possible.
Now I'm out on the same stream 30 plus year later, and even though I guess I'm using more primitive methods, I'm still doing well. Going back to roots? No, just adapting to changes in age, ease of use, and what works. I'll admit it's a heck of a lot more rigorous to fish this way and good for exercise, but not so good for subtlety, science or artistic satisfaction. I'm an artist in many ways, so it's also an admittance of age and taking the "easy" way. But that implies a judgement and maybe I made that on an inner level based on I don't know what.
I just know at this point it will take longer to get back into than it did to get started, and if it doesn't happen it's ok. Even if I just fly fish for bluegills that's ok. But I'm looking forward to getting on that terrestrial top water period soon. It was more like the run and gun fishing that I do just to catch fish, but a lot more relaxing.
I will always do all kinds of fishing as I've always done. Maybe I'll evolve, maybe I won't. But it won't matter and there is no comparing. I've caught so many species so many different ways, it's all good. I can't leave behind my foundation and diversity will up the odds. I wish I still had that patience for trout fly fishing.
I mentioned the old gents fly fishing with their canes and pipes. I have a feeling they are just glad to be where they are even if they stand in the same place and I walk by an hour later. Maybe I'll be there someday too, but I doubt it. I'm always moving. But I envy that they stuck with the fly fishing and it still works for them.
