Not yet. It's difficult to say if they would be more effective for brook trout in my area. Here, brook trout are like perch elsewhere. The limit is 20 brook trout of any size. They always bite and if they are not biting it's usually because they are feeding elsewhere or are very orientated towards one bait....usually nymphs and flies in my area or smelt that are sometimes found in the lakes close to the Saguenay river. The Saguenay is full of smelt and about 10,000 years ago, the water levels were very much higher. Since then, the smelt have become landlocked in some of the lakes.
