I think I read an article somewhere that after so many inches, your stabilizer length was just extra unneeded weight. I think it was 8".
That would be false. Almost the opposite.
You need to separate out the vibration killing function of some stabilizers with that of actually stabilizing your bow/shot sequence. They are two different things.
There is a better argument that any stabilizer less than 6" will offer little stabilization benefits. unless you are adding over a pound of weight.
Sometimes the trade off is worth it. If I am high country mule deer hunting or something like that I might look at setting up my bow with a short stabilizer that only focuses on vibration dampening and practicing with the bow that way. It would eliminate 10-16oz on my bow. However, my comfortable range might be shortened up some if practice shows opened up groups.

I am sure the results can differ depending on bow/setup and the person shooting. The only way to know if it will make a difference is to try one out. I wonder if you could demo one at Scheels and shoot on their range. Then you could see if it helps. If you pick one up, let us know if it helps. Good Luck!
Exactly, every bow and archer will be different as to what it takes to get to the best set up.
This is where just throwing a 8" bar with 8oz of weight on the end of it might do you no good, make it worse depending on the balance of the bow, or it could be the optimum thing to do.
You want your stabilizer set up, front bar and back bar, to balance your bow while also increasing the bows moment of inertia and pushing the center of gravity lower on the bow. All of this will reduce your pin float and, all other things equal, tighten up your groups(consistency).
Its a balancing thing though and like most things improving one aspect might hurt something else....
