To avoid getting lower on the swing is it as simple as not adding knee flex during the swing? Is it better to have more knee flex at setup so you can only go up?

I've been trying to limit my range sessions to grass as much as possible. I've found too much hitting off of mats to be detrimental to my swing. In particular I think it causes my angle to attack with irons to gradually increase if not very careful, most likely due to subconsciously not wanting to hit down into the mat. Foam balls cause me to lose face awareness.

How hard is it or how much time does it take to set one of these up each time on a grass range?
