[Dragon Ball Z] Why does the Frieza Force even bother with weaker soldiers (such as Raditz or the soldiers that Gohan and Krillin/the Namekians killed on Namek) that could easily be replaced by Saibamen?

Saibamen seem to have low intelligence/will, and probably only accept simple direct orders. Raditz and the fruit aliens can follow directions and manage logistics on their own. 

Also Saibamen probably dry up in the sun if you forget to water them or something.
