You can also try to twist your body to bring your flutter kick to a more horizontal plane, kind of like doing the side stroke. This should keep the silt down, and may not be as stressful on the knees, although I haven't done this extesively enough to learn of any drawbacks yet (I could see a problem with maintaining a straight course). Either that or try a simple straight legged scissor kick with a nice easy stroke.
