    The choice of weight that you use determines the response of the damping system.

    The lower frequency hand shock vibrations associated with the launch of the arrow tend to be reduced more with the heavier damper weights as it takes more energy to move them and often times the increase in displacement of the elastomer results in more low frequency energy absorption. Depending on the particular set-up these vibrations are generally in the frequency range between 100 and 200 hz and are driven by the set-up and the harness system of the bow.

    The higher frequency or ringing vibrations that can be initiated by the shot but may be due to individual components or accessories, tend to be absorbed better by Dampers equipped with the lighter aluminum weights simply because they respond better to and are more efficient at transferring energy at those frequencies.

    It is this difference in individuals and their bow set-ups that makes it necessary to offer the different variations in weights and dampers.

    I have some of the brass weights. Would they increase or decrease movement? Would felt vibration be less?

    Their movement may or may not be slightly different than the aluminum weights but even if the movement is the same, you could be absorbing as much as three times as much energy and I would suspect that most people would feel less vibration.

    That is the video I was looking for! The limb did not move at the thimb bolt even with it backed out! Now I just have to convince all my Hoyt shooting buddies to log on and watch it! I am SO tired of hearing how “the laws of physics say the limb woud Have to move with the bolts backed out!”

    You probably need an updated version of the Flash player.

    Another great video showing Mathews innovation at work. It also shows the only thing I was disappointed with about the Dren. The bow I shot at the shop was also a 70# backed down to 62# and as you can see from the video, the limb bolt just sits there exposed.

    Now I’m sure functionally it is probably fine but aesthetically speaking, being able to see the shank of the limb bolt just didn’t do much for me. It just appears that something is missing when the limb bolts are backed out. JMO

    neat vid. that really showed alot. it doesnt show it as an option when checking the specs but can you have the carbide dampers installed on the new Drenalin??

    What type of bow shooter is this thing in? The reason I ask is that the riser moves a lot. Is the riser actually bending or is the bow shooter allowing the bow to move?

    Some of you folks worry about looks a little too much. The bolt being exposed is an odd worry. I have folks saying they would not get a Dren unless they could get matching camo stabilizer/quiver/rest. Maybe I am just so pretty that I don’t have to compensate for my bow :^O (I used this icon because I don’t have the yaking one)!!

    I am pretty sure this is done out of a hooter shooter. All risers flex under the forces from the limbs and string. Kinda neat aint it. I would imaging Carbon fiber risers can flex a lot more. It would be almost impossible to make a riser that doesnt flex under full draw that the average person could hold and shoot. Dont worry about it. Every bridge you drive over, even skyscrapers are all engineered to flex under load.
