As nubo suggested, check out the Stealth Stabilizers. I had a 4" built for me and I gotta tell you, this thing amazes me! It weighs 6 ounces but takes out more vibration than my 7" 9.2 ounce Doinker, by far! I was literally amazed when I shot this thing! Jerry makes ONE HECK OF A PRODUCT!

I think that 4" and 6 ounces is about as light as Jerry can go! He uses a dual chamber design in the Stealth Stabilizers. The large chamber is designed to remove vibration from the riser/limbs of the bow while the smaller chamber is designed to remove vibration from your accessories (sight and rest)!

A custom 4" 6 ounce Stealth will run you $59.90 (with shipping included) and it will be at your door in less than a week! I ordered mine late last Saturday evening and it was at my house Thursday morning!
