I assume you live in Atlanta, GA. I recognize your name, but don't remember any details. You probably know what I'm going to ask...
How often do you water and how much?
How high/low do you mow and how often?
How often do you fertilize and with what?
Are there specific weeds you're having trouble with?

I'll bet you read my post over at that other lawn care web site.

As long as they are used properly, no, I don't see them as being detrimental to the health and vigor of bermuda. I guess they can impact root growth of bermuda in spring transition, but that does not always translate into issues with nitrogen uptake.

The advice to fertilize and mow frequently and avoid pre-m's that was given by the gentleman at the other site is sound,(and to that I would add aerate and topdress at least twice a year) but it just isn't practical for most folks. And what is more detrimental to the health of your bermuda, semi annual treatments with Dimension or Amaze or constant weed pressure from poa, crabgrass, etc..

You could could avoid the whole question and use Ronstar, but it's expensive.

I would avoid top dressing period - unless you are using something that is 100% organic. Top dressing with sand or top soil will build up and give you a mound instead of a lawn. Organic materials eventually disappear leaving the original soil levels. Here is a picture of a lawn where they top dressed a quarter inch every year for decades.

You can see in the back where the soil has washed over the sidewalk so that the lawn and hellstrip are joined with a patch of grass. It doesn't show up from the angle of that photo but the grass at the sidewalk is 2 inches above the level of the sidewalk. About 3 feet to the right (out of the photo) the grass is a full 8 inches above the sidewalk. Routine top dressing is not a good practice.

Routine top dressing of grass on golf course properties has been going on for at least 25 years. Done correctly it causes no harm to existing turf, can be beneficial, and will not give you as you said -a mound instead of a lawn.
