How do you guy shoot the mirror? I was shooting a tennis match this past week, and my tripod's pan head just was not loose and smooth enough to be able to track the players. Quite frustrating. I just ordered a Neewer gimbal from Amazon, to try out. BTW, I was shooting at a court, 6 courts away from me, so I needed the reach of the 500 mirror. The 300 was a bit too short for that distance. I was pleased with the reach.
