3,4,5 weight is good for around here!
Weight forward floating fly line for dry flies
Sink tip usually for wet fly or nymphing
I’m not a fly fishing expert but pretty sure that’s a good start for you locally
I agree with Corn Field Killa
To simplify things to get started without breaking the bank.
1) 9 foot 5 Weight medium action fly rod.
2) Fly reel, that depends on your budget but get one that matches your 5 weight rod.( they also come in different sizes)
3) Fly line and backing- for all around fishing you can use 5 weight, weight forward floating line. 20# Dacron backing.
4) 9 foot leader and 5 x tippet
This list will be able to get you on the water to fish dry flies, wet flies, nymphs and streamers with this one setup.
You can also buy a beginner rod and reel outfit from any fly shop or sporting goods store.
As far as casting if you need some lessons, go on you tube and there's a ton of videos.
Hope this helps
