If you are asking me, it’s X-56 with no buts nor doubts about.
I used a -52 for more than a few years, but the-56 has been a real upgrade - and I am using it still, even after changed the stick with a Warthog one, because it’s more versatile. I changed something to make it more stiff and precise, but the same… it’s here, a rock.
My one little Euro cent here.
With best regards.
