If I could make a suggestion on what to try....I use these on my 3D bow, I have made some modifications (I have doubled the length on my 3D bow) but these stabilizers come with some additonal weights to play around with too.
Cabela's carries them and so does Jimbows in Calgary. The 9 inch one runs about $50-55
