Coded animmation HELP PLEASE

Question

I am having a hard time figuring out why the lines that are
crossing each other get jerky after you watch it for a little
while, and why there becomes a big space once the green lines
start. I think it has something to do with the lines not deleting
after they get to the end, so it is just taking up a lot of virtual
memory. Any help would be much appreciated. Here is the code I am
using and the link is to the .swf so you can see what I am talking
about. BEWARE, once you leave the .swf open too long it may freeze
up your internet browser.
i = 0;
{_x:193, _y:119});
function tweenBall() {
attachMovie("Line_mc", "Line"+i+"_mc",
this.getNextHighestDepth(), {_x:193, _y:119});
//trace("in function")
easeType = mx.transitions.easing.None.easeNone;
var begin = this["Line"+i+"_mc"]._x;
var end = 327;
var begin2 = this["Line"+i+"_mc"]._y;
var end2 = 270;
var time = 1.5;
var mc = this["Line"+i+"_mc"];
ballTween = new mx.transitions.Tween(mc, "_x", easeType,
begin, end, time, true);
ballTween2 = new mx.transitions.Tween(mc, "_y", easeType,
begin2, end2, time, true);
i++;
trace(i);
tweenBall();
function removeclip() {
for (j=0; j<i-1; j++) {
if (this["Line"+j+"_mc"]._x == 327) {
removeMovieClip("Line"+j+"_mc");
k = 0;
{_x:193, _y:119});
function tweenBall2() {
attachMovie("Line2_mc", "Line2"+k+"_mc",
this.getNextHighestDepth(), {_x:335, _y:277});
// trace("in function");
easeType = mx.transitions.easing.None.easeNone;
var begin1 = this["Line2"+k+"_mc"]._x;
var end1 = 200;
var begin3 = this["Line2"+k+"_mc"]._y;
var end3 = 132;
var time1 = 1.5;
var mc1 = this["Line2"+k+"_mc"];
ballTween1 = new mx.transitions.Tween(mc1, "_x", easeType,
begin1, end1, time1, true);
ballTween3 = new mx.transitions.Tween(mc1, "_y", easeType,
begin3, end3, time1, true);
k++;
//tweenBall2();
function removeclip1() {
for (l=0; l<k-1; l++) {
if (this["Line2"+l+"_mc"]._x == 200) {
removeMovieClip("Line2"+l+"_mc");
