Lol, If you really want to know, you can tie flies for icefishing too, just a matter of what your targeting and where!
I personally like using small flies as droppers to spoons (spoons make a lot of attention to get them near, flies are the fishes bait of choice)
As I mentioned, Buy things that work in the worst of the winter cold, That way you can use it in the summer too and carry on your addiction to all the other types of fishing!
If you are looking at purchasing something specific, I am confident if you ask the people on this forum they will be more than happy to offer you their advice/reviews!
