I started using them this year in conjunction with a III sink tip and find they really balance out the line and fly system, are a great help to get an unweighted fly down where I want it to be, easy to use, and very durable. I was surprised that something so flexible would readily turn over larger salt water patterns for coho, chum and sea-runs. Used them for sink tipping late summer steelhead too. All and all, its now a part of my normal sink set-up.
I've had no experience with using the floating poly leaders, and would be real interested in hearing from someone that has.
