To me, the wool is the real attraction. Why do we like things like wool sweaters and socks in the first place? Because they wick water. In the case of this indicator, a little dab will do. It rides high, but sinks quick on the tug, so it's super-responsive. Casting-wise, I think it slices through the air cleaner than a hard object, and it lands on the water surface with barely a splat.
