This is just a small point.

I have been happily using carbon tube stabilizers with doinkers on the end for all my stab an vibe needs. The Shrewd stabs I have come with a doinker and aluminum end weight. The weight is is nicely finished, but the screw hole does not go through all the way, and allow one to mounts extras on the end of the weight. I did the obvious thing and drilled/taped a hole through it and now it wears one of those simms stabilizer mushroom things on the end. The combination of the rubber doinker, weight, and simms is just perfect for killing any vibes. Its working for me.

Ossage,

I have a 4" Doinker on my MQ32 hunting bow. It works well as a vibration trap but it needs a little more weight to balance the bow. It has an threaded accessory hole in the end and I was thinking of putting on a Simms 'mushroom' on the end. Do you think I would get any additional vibration/noise dampening from this or would this fix just add more weight? Did your setup really become noticeably smoother when you added the mushroom?

I think it helps a little, but my bow isn't objectionable to start with. The Simms is a very much softer rubber, and the combination seems to be like an anti-woofer and tweeter: one sucks up the highs and the other sucks up the lows. The simms adds a lot of weight in the context of a 1oz aluminum weight, but it is all synthetic, and doesn't add much real weight. In my case it however doubles the weight roughly, and more than doubles the length ahead of the doinker.

My bow in the above case is a Mathews C2.

I am also experimenting with putting a heavy weight in the bottom and a light weight on top. Until now I have just used both heavy weights. I hope this will: Lighten the bow slightly; bias the bottom to help keep the bow verticaly aligned; kill different sound ranges on the woofer tweeter basis; and give me an identical heavy light set of dampers in reserve. Have you played with that?

Thanks for the tips and the info, Ossage. My MQ32 is from the generation of bows before the harmonic dampeners came out on the Q2, SQ2, Conqest 2, etc. so I don't get to play around with those shiny pieces of metal! Your idea has merit, putting the heavy brass dampener on the bottom and the light aluminum one on top.
