Can you use a Vectrosity points array with iTween?

So I have made a script which draws lines by user touch input with Vectrosity. Then adds an object to the line which follows it. However I am having some trouble with controlling the speed at which the object travels and also when it actually starts to move. Basically the object doesn't start moving until the count is over x percent of the array length. At least I think thats the problem but my code fu isn't that strong. So I thought by moving the object through iTween I could regain the control with something like MoveTo(object, vectorLineArray, whateverSpeed). But I am at a loss as to how to implement it and can't find much online in the way of merging Vectrosity with iTween. If anyone could help with either getting iTween and Vectrosity to cooperate or even just a better way to move the object which solves my original problem that would be great. Cheers
