I have tried all the bodies that rcfoolz has tried as well. I also have run the Losi and Parma Alfa's. I found the Losi Alfa to be the best of the 3, but the Alfa's were the worst of the bunch. Lots of steering, loose, but unstable and inconsistant. The caddy was also loose but consistant. I liked it and got my best qualifiers using this but I also got my worst quals. I stopped using this body because it was too hard to drive for long periods of time and exposed my car to too many risks on the track. The mazda was just the opposite of the caddy. Not enough steering. Very easy to turn consistant laps. I switched to this body because it was easier to drive for long periods of time. I didn't love this body, but it was the best I could find. The stratus 3.1 is great. I have not run any of the previous stratus bodies, but this one is awesome. It has steering close to the caddy and the rear is planted close to the mazda. I loved it on the MTX3 and I love it on the MTX4. For reference, I run on medium and large tracks usually prepped fairly well and I run only on foam tires.
