Looks like "just another stabilizer" to me.
They took design cues from several different stabs on the market.
I've been shooting a 10" Vendetta Enforcer with a 5" head for a couple of years. You can really tune the balance of your bow, and it doubles as a dandy kickstand when sitting in the blind. Weights can be moved from side to side, and you can also manipulate the weight bias by off set of the head. I threw a Bowjax on it just for fun, and a little color.

Kmon - I remember when they launched those mercury filled stabs 20 years ago, and I have always thought they are a cool idea (talk about the most effective damping material, ever!). Never did get around to buying one, and now they are darn near impossible to find.
