Two Lines or One.

[Steve7321]

The biggest reason is due to line management. Ice fishing and trolling is much easier to control multiple lines during the event of a hook up. Picture this, you are salmon fishing amongst the normal crowd of people and everyone has 2 lines that need to come out of the water within the same amount of time. We all know how frustrating it is when you get hooked and your lines cross and tangle and with extra lines in the water there will be more fish swimming around with lengths of line and tackle tangling up on everything. If we had an extra set of hands then I don't see any problem with 2 lines. But that is just my views.
