I'm not sure that should change your mind about things, it really isn't that big a deal but nevertheless it is true.
Only if you don't compensate with a lower print speed.

Higher mass does not equal poor prints. Highter mass equals a greater chance for poor prints if you don't use a speed appropriate to your mass and acceleration.
