I use this setup as well and printed a 7cm curved extension for it, gives an even more smooth and accurate movement of the stick. Only thing is, since i have it centre mounted and low in front of my seat, that with the full range movement the stick is al little bit hampered by my legs. Especially when moving the rudder pedals.
I have not used the other cams or springs with it since i like the easy movement it has right now.
Kind regards,
WarPig
