I personally found the twist control in the X52Pro to be quite a discovery for Elite. I've been a hardcore sim fan since the Elite 1 years (Falcon 1 to 4, and lately the Eagle Dynamics sims, mainly Ka-50 Black Shark) and never used it, always preferring rudder pedals. In traditional sims maybe pedals are better, you don't have a real need for perfect precision in the rudder of a plane or a helicopter, half a degree more or less won't make a difference most of the time (only when aligning for a rocket salvo). But in Elite, that's precisely the difference between hitting your target or missing. The twist control allows for complete precision in that regard, and much faster, much more than my legs can handle.
Staying on topic, my plan for the X52 stick is making a complete multi-mode profile inside the saitek software. You can then put to use every button and axis (there may be some more keys to come in the future, the design papers for shields speak of front and rear shields on some ship designs, among other functions).
