I already ordered the flat pistons so I will give them a shot first. Once we get a new layout I doubt we will have that huge flat lander. The CSI would be fine then with a weight thicker oil maybe. The kit was very plush with with them if you could hit the down side of the jump. That middle jump is slow if you don't just jump out there. Thta's the first flat lander we have encountered. Its so much faster to jump out there we pretty much sacrifice it all to go faster..
