Superman's LTU5 Thread

[Superman]

I hope your health is doing well and it is nothing too serious.

Thank you for your concern, I really appreciate it.

I just wanted to confirm something. I'm the type of person who doesn't like being told what to do. I'm more inclined to do something if I come to it on my own time and thoughts, and more likely to not do it or have resentment if I'm told to do it instead. 

So which type of sub format would be best for me? So far I prefer ultrasonic and hybrid trickling stream.
