Sounds to me like the launcher is not dropping fast enough. I had to play with my shakey hunter quite a bit until I got it right but now it is great and I love it. Trophy Taker reccomends you have the launcher fully up the last 2" of the draw but I've heard some people had to have it up longer and in my case I have to have it up shorter than 2". You will probably have to play with the length of the cord to get this right. Another thing to watch out for is your feathers or vanes slamming into the launcher farther back on the launcher, I've found that you need a higher nock point, in some cases as much as 1/4". You might want to try shortening the cord first then messing with your nock point.
