X65f user reporting in. Best damn stick I've ever owned.
I've setup my stick to have a linear input, and I've found my best performance comes from having no deadzone. That way, even the slightest impulse gets translated exactly 1:1 in game, and when I got used it it, the ship became merely an extension of my own arm. Controlling my ship now is mere instinct, I want to move the ship and it just does it.
The only game I had any kind of problems with thus far has been Star Citizen, and games in excess of 10 years of age (guess what connection i made there

). Theres also been a handful of games that have locked in deadzones, those kinda suck but fortunately I havnt found one I actually cared about playing.
All that said Cmdr Shoogalumps, I would think very deeply as to WHY you want the X65f, how you will use it, what the stick is doing for YOU and how YOU want to play. The X65f is a very
very different kind of stick, and it definitely one of those that people either love it, or hate it.
There are some definite drawbacks. I may have said it was intuitive, but for some it can take weeks of training to become accustom to it, playing with the settings and getting a "feel" for it. Most people's experience is like this at the start, but when you adapt movement and input becomes as natural as if it was a part of your own body.
Me personally, it didnt take very long for me to adjust, I had it down pat after only a few days of fiddling with the controls. But then again, I knew exactly why I wanted it and what I was getting it for, and it wasnt for its pretty metal enclosure.
The fact that the stick is force sensitive also means that the stick itself has to be ABSOLUTELY ironed in place. Unless you have an (extremely) light touch, the stick can and will move around on you. I personally have a belt that I strap it down with and that does it. The stick also has its own base plate and screws you can use. I recommend that method if you can (i'm just too lazy, and deal with the occasional slip).
Then theres also the fact that some just never really get the feel for it. Many people (most I'd dare to say) just prefer the tactile input of physically moving the stick. You get none of that with the X65f. Its just a direct input from the force exerted on the stick.
I also wont say that its any more (or less) accurate than another high quality stick. The stick is however extremely precise, as good as any warthog or CH stick I've ever seen, however experience aside accuracy in controls comes almost entirely with the users comfort and familiarity (excluding devices that are broken or just bad). Thats why some people are just better at FPS with a controller over a mouse, and vice versa.
All that said, you shouldnt pick up the X65f based on aesthetics, its a recipe for a wasted 350$. It's practically a lifestyle change. However, if having a pseudo physical connection to your ship and the prospect of force sensitive input is something alluring to you, its worth considering. You just have to understand what it is and believe in why it would be good for you, then commit to that when you get it even if it takes awhile for you to master.
