Rigid Shapes collision

Hi,
I have been trying to make a pool/snooker game using torque for the past couple of weeks and have decided to use the Rigid Shape class (http://www.garagegames.com/index.php?sec=mg&mod=resource&page=view&qid=5495). At the moment I have just made it so that the balls can be pushed around by the player (temporary). My problem is that when the balls collide with each other they seem to rebound off at weird angles. The code i'm using in the onCollision method is below. I'm fairly new to vector math so someone with a little more experience in that area may see something that i'm doing wrong...

thanks guys in advance,
Harley.

function SnookerBall::onCollision(%this, %obj, %col)
{
if (%col.getDataBlock().getName() $= "SnookerBall")
{
// Apply an impulse to the object we collided with
%eye = VectorNormalize(%obj.getVelocity()); //PROBLEM HERE?? This was meant to get the direction of the ball

//How hard the ball is hit. TEMPORARY
%power = vectorLen(%obj.getVelocity());
%vec = vectorScale(%eye, %power);

// Heres the position and rotation
%trans = %col.getTransform(); .
%pos = getWords(%trans, 0, 2);

%col.applyImpulse(%pos,%vec);
