Driven by irrational exuberance.
I'm going to Sweden in late June for midsommer and to meet all the in-laws. They want to take me fishing on their lakes for perch and pike. Their perch are the old world Perca perca, but the pike are the same species as North America. I have some ideas for pike flies. But what do you need for leaders? Do you need to go with wire, or do you go with a heavy mono shock tippet?
