Modify Elastic parameters

Question

I'm useing "Elastic" as a easer for a Move animation.  The elastic bounces a bit too much for my taste.  Is there a failry easy way to modify the amount of "bouncing" it does?  (I'm going to post this as another question as well, regarding the public variables)
mxml CODE to define animation/effect:
 <fx:Declarations>
 <s:Move id="moveRight" target="
{blackBox}"duration="
1200"xTo="
{changeX}"yTo="
{changeY}"easer="
{stretchIt}" />
 <s:Elastic id="stretchIt" />
  </fx:Declarations>
AS CODE:
// incrementor variable to keep track of where the infoBox is currently[Bindable] public var currMS:uint = 1;[
Bindable] public var changeX:Number = 0;[
Bindable] public var changeY:Number = 0; 
// Keeps track of the current MileStone // main function including case statementspublic  
function chooseMS(event:MouseEvent):void{
switch(currMS){
case 1: // to Milestone 2 
//blackBox.move(50,130);currMS++;
changeX = 50;
changeY = 130;
wgText.text = ebs_newMS2;
ow2.visible =
true;wh2.visible =
true; 
moveRight.end();moveRight.play();
break;
...  the rest of the switched cases are here...

Answer 1

I extended Elastic and override the ease() function.
To achieve the effect you see in the sample code, I changed the amplitude to 1 and the period to .6.
