The mount is incredible. I worked with Lucas originally on getting the SiTech integrated with the mount. The PE is incredibly smooth, the weight it can take is quite amazing, a C14 wouldn't even make it breathe heavy. He ships them well packed in a wooden crate and is very good to deal with.
If I had the money right now I would buy it over any mount in the same price range without hesitation.
What scope are you thinking of putting on it?
Talk to Olly or Yves about daily use, they are at an obs in France and have been using one for a long time. He calls his 'beyond paramount'
