Collecting can be it's own addiction!
Well, I'm a good one to give that advise! I've got thousands of flies. Probably more than I'll ever get to use. Nothing wrong with adding to the collection.
I tie most of my own. Been tying for a long, long time. It's addicting, and even though I have plenty of flies to fish with, I'm always tying more.
I'm a multi-species anglers too, so have flies for the various fishes I chase.
I enjoy the collecting & tying, which adds to my enjoyment of this sport. I'm sure you feel the same about ice fishing.
However, as I said previous, start with a basic assortment of flies & add as you wish. Proper casting, just as with a baitcaster, and presentation is more important than the fly pattern. It will take some time, patience & practice, but I'm sure you'll get it. Then you'll be like the rest of us & before long will have more flies than you'll use!
