I have not tried one of these, but it looks like you should be able to tie your fly directly to the wire tippet on this leader. I found the TyGer Leader website where they show the recommended way to attach your fly, either fusing the wire sheath or a 2-turn clinch knot.

I have used similar stainless steel leader wire and the knotable stuff, like TyGer, is much easier to use than the single strand wire. I have bought the knotable wire on a spool and just attached it to my mono leaders with an Albright knot.

Have fun with the pike!
