I haven't used it but I've seen many reviews. I don't like the look of the joint at the base of the stick and the "sticking" that happens moving from dead centre to give just a tiny bit of roll or pitch. That's the thing most people report is a major flaw with that stick.
Now I have a real actual person to quiz, have you noticed the sticking when you just start to move the stick from dead centre? Is it noticeable and will it lead to a bad gameplay experience in ED? Is it easy to make small corrections to heading in super cruise or lining up with a target with FA off?
The x52 pro has a different joint which makes it looser, but there isn't this sticking, which is why I wanted to go for that stick.
