Even less when wearing Trifocal progressives. The one thing I look for is a shadow on the ground, when I see it touch the field I know I have cleared it, problem is most times I am still too high to land easily and go long. Whats funny is prior to my last flight I was flying my LT-40 and did 10 T&G and put it right in front of me every time. With the SAME crosswinds, though the rudder on that plane actually makes it yaw.
