Pete, I've never tied crease flies before but I do know that this pattern is offered as a kit by many manufacturers. I don't know if they are offered in the 3/0 size that you're looking for, but it might be worth checking out.
As for durability, any crease fly that I have fished has held up fairly well for several bluefish before it got torn up and gave up the ghost. Does this mean they'll stand up to pike? I think it's a pretty good indicator that they will for more than a few fish.
Perhaps someone who has more experience with tying this pattern will chime in to help. Good luck.
