I was just about to mount my 50 Cals on the Sugar because I just got some Atlas Trucks that I put on my switch, and I like the Calibers a lot better for high speed right now. The Gullwing Trucks might just need new pivot cups, but I'm not sure if that will improve them as much is I want stability wise at speed. Ronin's or Charger 2's would be the upgrade I would do from here. They are all very durable, and fun to ride. What trucks do you ride, or what trucks would you mount?
