Man I don't know if an equpment adjustment is going to override the adreniline you have when you shoot at a deer. Your bow could probably weigh 100 pounds and it would still feel like a feather as soon as a big one steps out. Your technique is the problem and there is no way really around it. You have to be thinking follow through on a deer all the time but for what ever reason I don't get excited until right after I take the shot and then my knees start shaking. Maybe you could even try putting a sticker inside you limb that says FOLLOW THRU. Maybe seeing it everytime you raise your bow will level out your shots. Good luck.
