As a sidenote, the 162 is a freaking kite and pain in the ass to land.
I agree with the first part of this statement but disagree with the second.
Of the planes that I fly (172, 182, PA28, DA40) it's by far the toughest one to put it exactly where I want it.
Are you flying the same approach airspeed when you are light as you do for full gross weight?
