I had been using Rio Windcutter ll, until I found Hardy Marksman. It has out performed the Rio in every way. I have the WF4 and it seems to float higher than the rio, and I have not had a wicking problem with it. It did cost a bit more than the rio but it seems you get what you pay for in anything these day's.
I found the Hardy line at Montauk, and have used it 9 times this fall.
