Hi there Action, and welcome aboard. I use the ratchets too, and love them. I have chains in 1 cab, and although sturdy as all hell, it's also a pain in the rump. Ratchets are an ease to use.
I just upgraded to a 6.5' tall tent, but in my 5' tent I had problems loosing height with the ratchets. I just wanted to show you this to give you an idea and back up
@Anthropolis comment.
This is my current max height.

This is an example of the ratchets height lose.

This is what I had in the 5' tent.
Obviously with an LED you would have more height, but when you start adding pots, and lights, and the consideration of light distance from the plant, the tent start to get short really fast. Best of luck, and if you need anything just ask.
