Tweaking TU fragment settings

I'd like to tweak my settings for TU fragments but not sure what is a good combo. I've been getting a lot of noise as you can see below. Bottom 3 or 4 results are not needed.

Here are the settings for this project. How would you adjust the settings? I'd rather have tighter settings now as MT, TB, and AS wind up giving me too many options anyway.
