Toothless and love it. Toothless will skim more surface than other, toothless tends to be quieter. I made a simple creature guard of black nylon gutter guard by bowing it up long ways and inserting it down into my black acrylic weir, it disappears and stop migration into drains of any but the smallest animals which teeth couldn't keep out either.
