how well does the tyger stainless steal tie-able leader hold up to pike. is it worth getting over the titanium or flourocarbon leaders?

It works fine.  I started using Ti wire, though.  You can use thinner diameters, tie the same knots, and it doesn't kink.  It's very easy to use, and other fish won't shy from it as they sometimes will with Tyger.

What TI wire are you using??

What TI wire are you using??

When Pike are around I use American Fishing Wire. I just tie it using a uni knot and away you go. The coating does start to come off after a bit though.

He was using a Fluro leader.

As far as I'm concerned a heavy fluoro leader is better for pike fishing than mono. If you must go with wire, though, the AFW stuff is good.
