While it is a bit expensive, I have pretty much switched to short sections (3 in or so) of titanium wire. It knots well and absolutely will not kink. The problem with wire tippets is you may not have as much luck with the smallies. It may however increase your chances of actually landing the 48in pike that may be lurking nearby.

If you are tying flies just for the pike, use some long shanked hooks and tie on the rear of the hook only. This works well for bluefish in the salt.
