Thanks for the replies everyone. I have currently the Limbsaver Quads on my limbs and the Navcom Stabilizer. I also have a Meanv suppressor which basically has the same type of rubber material on the stopper.

I basically tested the effectiveness the same way you guys have. Added one item at a time and noted any difference in vibration and shock.

I am still rolling some ideas around on my experimental project with this stuff. More will come later.

Any other comments/info welcome.

Thanks, LT
