I just purchased the upgraded Sparrow from the Vanguard and I intend on getting one of the upgrades from Xur this weekend. I love just flying around on that thing. We need some tunnel or half pipe looking maps with lots of curves and downward hills. Maybe even some Sparrow specific maps with checkpoints so you can add some ramps and go back to them. Maybe even just a larger open ended map with jumps, tunnels and obstacles placed around the area.
