Fine control is also required to aim with the fixed weapons (and a twist axis provides a more intuitive feel), but when it comes to ergonomics, it's a personal matter.
I own a high precision flight stick with no twist (VKB Black Mamba - metal gimbal w/ magnetoresistive sensors) and (VKB) rudder pedals, but with Elite, I really enjoy controlling all the axis with one hand. I use my thumb on a hat to control the thrusters.
That's why I'm using a cheap
Logitech Extreme 3D pro with Elite instead of the top quality VKB stick/rudder combo. Nevertheless,
I won't recommend the 3D Pro because the gimbal is made of solid butter (ruining the feeling and overall precision) and the potentiometers tend to have a non-linear response.
The
Thrustmaster T16000M seems to satisfy many users but I have no idea how precise the gimbal can be and how fast it will loose precision (wear).
With the Black Mamba, I tried controlling the yaw with a hat (on the stick and on the throttle (Saitek/Mad Catz X-55)). It wasn't comfortable or precise enough.
From what I've read (and heard from some friends), the X-55 stick ergonomics are uncomfortable.
You may want to take a look at
Joystick Curves to ease your pain with the T-Flight Hotas yaw response (unless T.A.R.G.E.T already saves the day).
Imho, a proper yaw axis should be more enjoyable.
[EDIT]: the
Defender Cobra M5 is also a very good joystick but you'll have to find a v2 (not a v3) (
