Ok, I got this one. If you just want to fish pike then any fly will work. I did that for years, there is a lake west of Wawa OT CA. Magpie lake, you can catch 100 pike a day [ thats right 100 ] of all size, lots of fun. We now mainly use big flies 10inch and bigger and have noticed that we have bigger fish. We fish a lake where you catch some many 40 inch fish the 30's get no repect, a 30 inch pike is a nice pike. We did not catch fish like that untill we switched to the bigger flies. And yes we did get a 50 inch pike on a 3 inch fly. Look at the musky guys and the stuff they use, big stuff, they don't spend $20 on a lure for nothing. Consistently a big fly will get big fish. I use a 10 and 12 wt rods 400---500 grain rio DC line. I could save my arm and use small rods with small flies, but I want to fish for big fish and found that is the way to get it done. When I go pike fishing I have 5 rods in the boat ready, one with a small fly and get nice fish with it.
