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?
