In areas that do suffer from winter kill. Is it better to let the grass grow tall or keep it cut short. Is there any benefit to help prevent winter kill?

That’s a good question! I know that St Augustine do better if grown tall (tends to stay greener) in the cool weather. Hmm I remember reading about cutting bermuda low before spring comes helping green up earlier but i dont know about winter kill.
Some bermuda varieties plain suck in cold weather. A couple like Yukon and Rivera have far less winter kill % than others.

As the days grow shorter moving into fall and winter so also should the heigth of your turf. This mitigates the competition for the lower amount of sun light. I work my 419 down from 15/16ths to 7/16ths. An additional benefit of this is that the reverse is true in the spring, you want very short turf to begin so as to allow the sun to better warm the soil.
Also a shot of Dimension or some other pre-emergent in late October will keep those winter weeds at bay. Then the spring application in late February.
A tip for how to tell if bermuda is really dormant; just because it is brown does not mean it is. If the turf will burn unassisted when lit, it is dormant, if it just sputers and goes out, it is not dormant.
