I've seen references to "maxing out the downhaul". I am wanting opinions on what the delta is from downhaul-on-wrinkle-free to MAX-downhaul. How many cm's or inches do you add on to get to MAX. Not Ronstan numbers please because I have no idea how to convert that.

Are you 2 handing/2 feeting a 12:1 downhaul to get to MAX?
