WesternHills: "I'd agree with mgraber, on all points.
That said, I think "Knot 2 Kinky" is highly popular and very comparable option to AFW Surflon Micro Supreme, while being 1/3 of the price.

Yes, I agree Knot2Kinky is also a good option. Quite a bit cheaper, just as pike proof , just as small of a diameter, still tieable. It is a lot stiffer, so not as good with jigs and such, but fine with topwaters, cranks, any kind of trolling, etc.
