Hi Randor10,

I've got my XH A1 on an Action Pro. It took a lot of very slight adjustments over and over again but I finally got it to be ballenced. The spring is set to on and at the far extremes of the tilting up it still drifts. Maybe the XL1 is just too heavy for it.

As far as using the Action Pro for my XH A1 I love it. I found it to be far better than the Bogen 503 or Libec LS-38 in both the smoothness of pans and stability. I also got a cheap dolly to put it on and that set up works great. I had to change the wheels to rollerblade wheels so it would be absolutly smooth when moving but after that it worked great.
