I use a 4" stabilizer by Stealth Archery in NE. plus a single Sims modular stabilizer. Gave a friend a Doinker D2 4-rod 7" stabilizer in Hardwoods Green and she really seems to like it.
I've found that a combination of a Cobra Shockbuster to hold my sling in place, and one of the NAP Shockblocker's to be the best for noise and balance.
I Like the 4" Golden Key Tranquilizer for hunting it is short Light and silences the bow better than any other stabelizer I have used.
the second best I have used is the Oscillator by advanced archery which is no longer in business
My favorite #D stac is a 9" CarboFast from Holland
