I find that I am limited by the takeoff requirements rather than landing distance. I worry about runways that are shorter than 3500 feet making compromises on load or requiring more headwind to use them. With accurate speed control in my IV-P I can land and stop in 1500 to 1800 feet of runway (no obstructions, 4 on board 1/3 fuel, 95 knots on final, light wind, touchdown on the numbers). Takeoff (full fuel, 4 on board) to clear a modest tree requires more than 3000 feet.
