I target pike for a short spring season here in CT
But once the water warms, they hold in depths that makes fly fishing for other species look a lot more attractive.
Pike like flies..big wiggly ones.
I like both chartreuse and black, but you can't beat the combination of red and yellow.
You can fish with an 8wt rod.... I do,.. but you might want to use a heavier line. A WF9F or even a 10, depending on your rod. This will help you to throw the bigger flies pike like.
