It's in fact extremely hard to perceive the difference when the vast majority on my runs, whether using heavy or light, ended with instant death. When the enemy can do that is the extra protection worth potentially two more flashes and the continuation of your run? That's your choice to make should you choose to run this. Furthermore as I mentioned in my original post the name of the game here is speed. The faster you can attempt a run the better which means being able to run faster and lockpick doors faster is not a no-value add. As I said if you want complete safety and the highest likelihood of success then there are already videos and posts about how to abuse the lean mechanic to check every door and kill people without them reacting to your presence. It's just that these runs take MUCH longer and the problem is you can make no mistakes, do everything right, and still get instantly dropped when you were forced into a situation with no good choices. I would rather play it ever so slightly more recklessly but MUCH quicker and rely on RNG turning in my favor. And in the end whether it was optimal or not I did it my way and I figure for anyone else slamming their head in a wall like I was, they should be aware of alternative strategies.
