Im not sure how well that works. Personally Im using either yarn indicators
(unless it very windy), or
preferrably the Pop Tops. The latter have the advantage of helping me determine
wether or not I have drag free drift.

I've had bad experiences with a number of the twist-on indicators. One brand
had a tendency to split
easly and once I had to discard about 50% of a batch even before using them.

So far, two books I'm reading on fly fishing do NOT mention strike putty.
But, Orvis sells it, so it MUST be worth having, right? :-) Seriously....is
this stuff ever really useful, or do other fishermen laugh quietly when they
see it being used?
