Danko, I am a fan of the CS Prop. I like the resulting performance on my boat both sailing but especially under power. Currents, Passages etc are a way of life up here. One plans for them, watching the moods of the moon, times of the day and the variations of weather, yet there comes the time you may need that little bit of oomph to miss the boat eating whirlpool. That is the moment I like the CS prop best....
