Todd,
We have a geotex runway as well and I can tell you that if the ground underneath is not hard packed solid, it make a huge difference in the way the plane rotates as well as landing.
We put 350 ft in and then a year later added another 200 ft. The ground below the newer section had no clay and to this day is still softer. I have a much harder time rotating starting from that end than the older end. On landings Its almost impossible to land in the newer section, the drag has put undue stress on my landing gears so I can only fly if I have headwinds that allow touching down in the old section , then rollout. Bet you'd have no problem on pavement.
Beautiful jet!
Marc
