Does 13g make a difference? Sword X to EC2

I've mained a Sword X for about a year now and I love the shape. I've been having some problems with the mouse since I dropped it and want buy a new one. Since the EC2 is the "Original" I was thinking of buying one but its way heavier than the SX (47g vs 60g). I mainly play aim trainers so im worried that it will be significantly worse to aim with it. Any advice?
