Catching the pike will not be the problem if there are plenty of pike around... Catching multiples on the same fly might be. I would suggest rabbit strips to get the motion as it will last longer against pike teeth. Marabou is wonderful stuff for catching pike, but it does not last well.

Otherwise, you are definitely on the right track.

Long shank hooks will make it easier to unhook them and wide gapes will make it easier to hook them in the first place. Don't be afraid to tie them on jig hooks as they produce a lot of up and down motion when strip-retrieved.
