Depends on the bow , bowtechs most popular risor patriot/liberty/allegience is natoriously top heavy and in my hand needs weight in the rear hole of the risor , a short stabilizer works well to balence .They allso work well at sound/vibration reduction . The older forward faceing limb design bows balenced great with a longer stabilizer on th front of the risor , allso the added weight helped with recoil/jump.
