Sorry Primitive I beg to differ. The only thing on the Drenalin and I know for a fact it was tight. There was a noticeable difference between the XT and the Drenalin when it came to hand shock and string buzz. But IMHO that is due to the overall lighter weight of the Drenalin. Heavier weight bows soak up more noise and vibration. Just like arrows do. I didn't hate the Drenalin I just thought it was not worth giving up an XT for.
