How can I apply onComplete to GTweener (gskinner) ?

Hi,

I am trying to add an onComplete with staticRate to the (gskinners) GTween in an attempt to Optimization the SWF Framerate similar to what Lee Brimelow has done in the following project (http://www.gotoandlearn.com/play?id=112) . My action script is below.

- PS

Please let me know if this make sense ... maybe I am asking the question incorrectly.

Thank You for your help.

public function staticRate():void{
stage.frameRate=5;
}

public function animationRate():void {
stage.frameRate=30;
}

private function onClick(e:MouseEvent):void {
trace("BUTTON: SINGLE CLICKED");
animationRate();
var tw:GTween=new GTween(container,0.8,{rotationY:Math2.toDeg(e.curr entTarget.angle+Math.PI/2),z:100},{ease:Exponential.easeInOut,delay:0.1});
