Drawback elimination with fixed clamps
Another way you can reduce drawback if you have fixed clamps is to slightly push the base of the clamp slightly toward the tension head. Be very careful it is possible to add tension pushing it too far. You want the clamp to tighten slightly when you clamp the base and when you release tension it should drop back to the point where the clamp was without the base tightened.
