I have the leeches on my Hoyt. I've heard they cost you speed. Then I read an article that said they actually gain 1 - 2 fps. I've heard people say their bow is no quieter with the leeches. Others say their bow is dramatically quieter. They do have the potential to hit you in the eye. Sims warns you to wear eye protection which nobody does while bowhunting. I shoot a heavier arrow and use the S coil stabilizer. What would happen if I took off my leeches?
