Dimethicone viscosity (CPS) for anti-soaping, does it matter? What's best?

Wondering if it matters whether you use 1% 1000 CPS Dimethicone or e.g. 350 CPS for anti-soaping purposes? I really can't tell much of a difference, any reason to use one over the other?

    The way I understand theory, a lower viscosity dimethicone is more mobile (faster diffusion to where it's needed) whereas larger molecules (high viscosity) have a greater impact as antifoaming agents once at the place of action. It's an act of balance and a factor of 3 isn't that much of a difference if you ask me.
