What's the best PS to use for rushing water?

[Mackiiboy]

When I created a waterfall, I used the entity "sewerduct_water.ent" for the waterfall, and "ps_impact_water_wheel_splash_highest.ps" for the splashes. I modified "ps_impact_water_wheel_splash_highest.ps" in the particle editor to improve the splashes and make them to fit better with my waterfall, which is something I recommend you to try if you want to have a good-looking waterfall. You can place some of them on the water, and some of them under the water to improve the splasheffects.

What's the best particle system to use when you have rushing water? Like a waterfall?
