RE: Slowing down after landing
I took a completely different approach. I used to have a 10 foot high hedgerow that I would have to clear before I could set it down on the runway. I rented a bulldozer and ended up doubling the length of the runway by knocking down the hedgerow, filling in a ditch, and clearing brush for about another 150 yards. If you don't make it down in the length of the runway now, it's because you're still doing over 100 mph at the threshold.
I used to have to waggle the rudder to eat up speed once I got it on the ground. That did work for me.
