This is a great tool. I used these (usually use CF Black Prophets w/leashes) on moderate water I and I was very pleased. The curve in the shaft makes sinking tools a breeze, they just fly right in. If there's a downside to the tools, it's that the pick is so easy to place it can be easy to over-sink them and make them difficult to remove. Once you learn to deal with that though, it means less energy spent all around.
