Hi cub682,
I’m not sure what your budget range is but latex is a more costly material than polyfoam or most memory foam.
[quote]What do you think about this one in a synthetic queen? It is dunlop and I’m not sure. With my current comfort level and my weight, do you think I should go with the medium firmness?

This is synthetic Dunlop which is a lower cost version of latex compared to natural Dunlop or Talalay but it’s certainly a good quality material compared to other types of foam and is a good “lower budget” version of latex. You can read a little more about the different types of latex in post #6 here but it will really boil down to your own preferences between the different types of latex and your personal experience.
I would use the topper guidelines I linked earlier along with a more detailed conversation with a supplier you are considering (who will know more about how their materials compare to others than anyone) to decide on the thickness and firmness level that in combination with your mattress has the highest odds of success.
When it comes to comfort layers and toppers … then “just enough” thickness and softness to relieve your pressure points when you sleep on your side is usually the least risky choice in terms of alignment.
