Cougar, first let me say that I have 5 of the stealth stabilizers and they are definantly the best I have ever used as far as absorbing shock and vibration on a bow. They are designed with a 60/40 weight variation to better balance your bow or you can also turn it around if you prefer. If you add this stabilizer to an already quiet bow, it becomes DEADLY quiet. If you want to check them out go to www.stealtharchery.com, or give Jerry a call at 402-304-1899, and he can explain his design to you far better than I can. He can custom design a stabilizer for you in a length and weight that you prefer, and he is a great guy to deal with. If you try one of these, I honestly think you will be impressed. He also frequents this board as stealthman. Good luck, and hope this helps.
