I fly fish a lot in Utah, even for crappie. Trout are catch release, crappie for dinner.
I'm avid user of 7-8 WF floating line weight and 5 lb 9 ft leaders. I use mostly streamer flies and small jigs with or without a strike indicator, another term for fly fishing bobber. And, chances are of hooking a carp, striper, catfish, or bass is very possible. Heavier rod/ line handles all things possible.
You shouldn't spend a lot of money on gear. Practice in open yard areas, with light wright on end of leader.
Roll cast is essential in covered areas. Wading, float tubes help get to open water.
1/32 and smaller jigs,super glued 1.5" soft body.
Sometimes no bobber slow sinking jig hit right depth and floating line will pull forward on strike.
