Why? Because I have lots of it, and I don’t have many flies, and I know power bait floats the same as a fly would. I also know the hatchery fish here seem to like the yellow kind. This particular body of water is open to fishing year round.
The distinction between bait, jigs, flies, etc. is one that I don’t understand. They’re all synthetic materials (unless it’s live bait, which powerbait isn’t) so why are they treated differently?
Understandable that you want to use the stock of bait that you have, and I agree that the availability of artificial lures, flies, and various kinds of bait can be overwhelming. It will help to keep in mind that the difference between fly fishing and using a spinning or baitcasting setups is not just technique, or even the basic gear, but the tackle, start to finish. The fly rod and reel are designed for fly line (and backing line!), special tapered leader, and tippet. And what you put on the end of the tippet, whether wet or dry "flies," is in a separate category from all the hooks, bait, and lures that you would normally use for spinning reels or baitcasters.
I only started flyfishing a few years ago, and have lots and lots to learn, but one of the things that struck me right away was that the complexity had far less to do with casting technique and more to do with the nuances of terminal tackle and choosing that tackle to best meet the needs of the existing conditions.
I think it also helps to understand that the tradition of fly fishing has been to fish with flies that closely mimic the actual creatures that fish feed on (although I think there's some elasticity of definitions here). In some ways, too, fly angling seems to come with a belief that it should be challenging, not easy. (And for that reason, the purist of the pure seem committed to dry flies only even when 90% of a trout's feeding is subsurface.) I'm not a purist and am all for doing what works. But even then, fly fishing is much more about fishing than it is catching (as the old joke goes).
Anyway, I hope that provides some insights into what makes flyfishing unique.
A great book to help with the basics is Tom Meade, Essential Fly Fishing. It's a great primer, start to finish, and includes the basic knots you need to know, especially the Duncan Loop (also known as a uni knot) which is absolutely crucial for tying your fly to your tippet.
Good luck!
