Anyone who wants to see an AWESOME (wash/rinse/spin) Kenmore DD washer with a straight-vane agitator check out YouTube. The name of the video is called Dirty Laundry!-Washing Machine Timelapse Video.
YES! Isn't it kool. I never knew how strong the rollover was from the straight vane agitator. Once I saw this video, I was hooked. And wanted the agitator for my machine.
