The other day I was at my dealers and he gave me a dvd to take home and watch that bowtech sent him.It was called the 2004 bowtech dealers tools dvd.Well in the dvd it explained that although the vibrablocks could be positioned anywhere on the limbs they were designed to be slid right up against the limb pockets.I slid mine down to the limb pockets and it is even quiter and more shock free than before!I had also had my cable rod muffler pushed all the way to the slide because I thought it was made as a stop for the cable slide.Bowtech said it should be positioned far enough up the rod so it doesnt make contact with the cable slide.That made a big difference too.Hell I thought my bow was quiet and smooth before now when I add some limbsavers up where I had the vibrablocks the arrow will be through the deer before I even realize I have released!!
