My most expensive complete outfit (Sage rod, reel, case, & Rio line) cost around $400 new, and my least expensive (Eagle Claw rod, Pflueger reel, eBay case & line) cost around $60 new.
I enjoy them all!
The only trout I've caught was stocked rainbow in the local lake and I've actually used live bait for those.
I used spinning or baitcasting tackle for over 40 years before I tried my first fly rod, and within a year I sold/gave away/retired all my spinning tackle.
If I need to zip a lure swiftly through the water my baitcaster(s) will handle the job, and the fly rod(s) get used for over 90% of my fishing.
I carry my nippers, floatant, flies (small fly box), hook file, and forceps on a neck lanyard and spare tippet, leaders, line cleaner, and a few other accessories in a small fanny pack.
Cheap insulated hip boots handle my cold water wading, and canvas shoes handle warm water wading.
I fish almost daily, catch fish almost daily, and find 6" bluegills beat the heck out of catching nothing if the bigger fish aren't biting.
Matter of fact - most of the bigger fish are caught while chasing the bluegills.
(A trip catching bluegills over 8" and I'm really excited.)
When I want fish to eat I'll grab the baitcaster and target channel cats, but about 2 a year is all I keep. Everything else goes back in the water.
