Simms stuff all works for the most part. I won't own a bow without limb savers, period! Doesn't always cut down on the sound, but always makes a difference in the way the bow feels.

And there are various stabilizers on the market that reduce vibration, shock and recoil. You just need to try a few and see what your bow likes the best.

I have also had good luck the NV system.

Others seem to really like the systems that mount to your riser and stop the string, like the STS or the MeanV products.

Heavier arrows and adequate string silencers help a lot as well.

Did you have a specific product in mind?
